While we still have some time left to kill before football, there's some leftover football sitting right there on the YouTubes, and some of that leftover football features future Michigan players. With more high school games being uploaded in full these days, we're going to be doing more single-game film breakdowns here, starting today with last year's game between DePaul Catholic, featuring 2016 signees Kareem Walker and Michael Dwumfour, and Bergen Catholic.

DePaul fell 15-13 in a tightly contested game, and they may have pulled out the win if Walker hadn't sat out most of the first quarter for undisclosed reasons. He managed to break the 100-yard barrier anyway. Here are all of his carries from the game edited into one video:

As we learned during his late-cycle rankings plunge, Walker isn't a no-doubt prospect like Leonard Fournette—the eye-popping runs are largely absent from his highlight tape. Seeing him work over the course of a full game, however, improved my perception of Walker. His vision was very good, and he does subtle things that will become more apparent on the next level; I love the way he patiently set up his blocks like he did at the 0:55 mark.

Walker's acceleration is solid when he picks his spot to go. While he runs upright in the open field, he does a good job of getting behind his pads to get through tackles at the point of attack, and he uses his off-arm well to shed arm-tackles from defensive backs. When it gets down to it, he finds a way to get upfield. He's not the most explosive back, nor is he the most powerful—he could definitely add some muscle in his lower half—but I like his potential to be a productive college back; the instincts that Michigan's backs have often lacked of late are present in Walker.

As for Dwumfour, he mostly played right defensive tackle, and he's relatively easy to pick out in these clips—he's the only DePaul D-lineman wearing white gloves and white cleats/spats. Before posting this video, a caveat: this is every snap I could get a clear view from Dwumfour (all but 6-8 snaps he was out there, best I could tell), so don't look at this the same way you'd look at a highlight reel—a highlight reel would contain maybe three or four of these plays.

Let's start here: this was a rough game. Dwumfour has a bad habit of bolting upright after the snap, and in this game his opponents capitalized by stonewalling him again and again—there are a couple plays on which he literally gets turned around 180 degrees after the snap (and one more that didn't make the video because ESPN cut to the play too late). On a down-to-down basis, he wasn't very good—he didn't have the strength or motor to overcome his obvious lack of technique.

Of course, Michigan isn't recruiting Dwumfour to be the player he was in high school, and you can see flashes of why they took him that aren't "is best friends with Rashan Gary." Dwumfour has a quick first step and a couple of moves that can get him into the backfield in a hurry. When he does fire out low, he moves people, but he doesn't appear to have much technique that would allow him to disengage—something that can be corrected.

It's not surprising to me that Dwumfour was a generic three-star. He's a big body with athleticism, but there's a lot of work to do to get him to the point where he can contribute at the Power 5 level. Michigan shouldn't need him to be an instant-impact guy, and that's for the best; I'm not sure he'll be ready to play more than scattered snaps for a couple years.
