Tape Breakdown


I’ve been a big believer in Marlon Mack for the last three seasons at South Florida, but I had no idea just how special he was as a game-breaker every time he touched the football over three seasons with the Bulls.

In a draft class loaded at the running back position, Mack just might be the most explosive back in the class with the ball in his hands, and that includes Stanford’s Christian McCaffrey, Florida State’s Dalvin Cook and Oklahoma’s Joe Mixon.

Just pop on the tape of Mack and you’ll be blown away.

Standing at 6 feet tall and weight just north of 200 pounds, Mack has the ideal frame for the position and even has some room to add extra bulk in the NFL should he need to, but what really stands out with this guy is his terrific footwork in the hole, leading him to daylight to turn on the afterburners in the open field.

In the clip above, Mack shows you just what he’s made of as you seen the good footwork in traffic to work back to the cutback lane that he sees thanks to his vision, and from there it’s just vapors for the Temple defense, led by current Steeler linebacker Tyler Matakevich.

Mack made a habit of just running away from people in the open field, and if he wasn’t able to fully pull away from guys, he has the power to keep defenders off of him.

The junior was just a man amongst boys for much of his career at South Florida, and that run against Central Florida above from this past season just sums up his career in a nutshell.

Once he gets the handoff he’s patient enough to let his right tackle work to the second level to get on the linebacker, which gives him the big lane once he’s able to shake free of the UCF defensive tackle that’s on him quickly.

His speed is NFL-ready right now, but it’s his strength to fend off defenders and run through tackles that should allow him to have a productive career at the next level.

Although Mack ran exclusively out of shotgun in USF’s read-option system, but he’s so shifty in tight areas and has great vision as a runner to see lanes opening up that I don’t think it will matter what scheme he lands in at the next level.

Almost as soon as Mack gets the football here he has a defender waiting to make the stop behind the line. But because he’s such an explosive athlete, he’s able to quickly bust out a spin move and get around the edge to pick up a first down in the process.

It might only go down as a 10-yard run in the game log, but this was one of the more impressive runs I saw from Mack in the nine games that I was able to get my hands on.

As I mentioned earlier, Mack is a patient runner when he needs to be, but there are times where he’s too patient and runs right into a big tackle for loss. A lot of that can be attested to him trying to hit the home run on every carry, which can be a boon to his game at times.

He has a lane between the left tackle and left guard to get into the second level, but he just simply doesn’t see it. Mack definitely needs to learn to just put his head down and get positive yardage in situations like these instead of worrying about a house call, because by searching for a lane to find pay dirt, Mack racks up a big loss behind the line of scrimmage.

Although he has the speed and wiggle to get to the edge or make guys miss in the backfield in college, he simply can’t rely heavily on that in the pros because guys are faster and stronger at the next level, and obviously the NFL is a massive jump from the American Athletic Conference.

Along with his propensity to always try and hit the home run even when the situation calls for it, Mack really struggled with ball security in the nine games I watched of him. The junior fumbled four times in that span and really tends to hold the ball recklessly in the open field.

Outside of that, Mack doesn’t seem to want to get physical in pass protection and largely relies on the cut block if he’s in the backfield on passing downs, which was rare despite not being a great receiving threat.

When not in the backfield as a pass protector, Mack loves to throw open field blocks to spring teammates to daylight, so it’s very strange that he appears overly uncomfortable in pass protection.

He’s not afraid to get physical, so that can’t be it. It’s hard to put a finger on.

Overall though I think Mack has what it takes to be a legitimate running back in the NFL that a team can build around in a timeshare until he develops more as a receiving threat out of the backfield.

The speed, vision and elusiveness alone should have NFL teams excited about getting a crack at him towards the end of April.

    No GIFs, just links to youtube.

  • Steelers12

    i think there are better options in this deep RB Class

  • steelburg

    I really like this guy. He is very explosive as a pure runner and he is good enough in the passing game although he could use a little more work in his hands. But his blocking is a issue and will need to be worked on big time.

  • MoSteel

    Big fan of Mack, especially since he could probably be had in the Rd 3-5 range due to the depth of this class. An improvement over Toussaint imo and room to grow. As a fan and alum of USF I was surprised he didn’t return from his senior year but maybe that could work out for the Steelers fan in me

  • CP72

    Le’veon is a lot of things, but fast isn’t one of them. Be nice to add a little speed to the position.

  • Spencer Krick

    I can get behind drafting him.

  • SilverSteel

    This guy is really athletic. I wonder what round he is projected at.

  • LucasY59

    in the 1st gif I think Reddick (#7 LOLB that comes off his block just a little too late as the RB is breaking through the hole) is the guy that had the best chance of stopping Mack, but Marlon goes untouched

    since there is so much interest in Haasan thought I would point it out (not really his fault, just a great play by Mack)

  • LucasY59

    agree a homerun threat at RB would be a nice addition

  • LucasY59

    the negative parts of his game are really concerning, ball security is a big deal, and lack of usefulness in the passing game both as a blocker and a pass catcher make him a less than ideal fit in the Steelers offense, if he didnt require a early pick I think they could add him just because he could be a threat to break a run for a TD (especially if he came in after Bell had been wearing the Defense down)

    I dont like the off field stuff with Joe Mixon, but I see him as a much better fit for the Steelers (and since he has issues he could be a later draft pick, I wouldnt take him before the 5th, but at that point the risk is worth reward IMO)

  • TrappenWeisseGuy ;

    Hes probably faster than you think but with his running style he rarely gets up to top speed. I know, same effective result. If Karlos can stay clean I think he could offer this type of change of pace type running.

  • Shannon Stephenson

    One of the biggest reasons why decent college HB’s do not make NFL team rosters is because of blocking. Too many guys in this draft that show good ability blocking in the passing game instead of gambling on this guy.

  • Josh Carney

    I’d be stunned if he’s still on the board to start the 4th round.

  • Josh Carney

    Nailed it.

  • Rocksolid20

    4 or 5 and he is a steal if he can be had at 5 !

  • Joeybaggadonuts

    Woo! Get him on the Juggs machine! He would be a nice 1-2 punch!
