Jim Harbaugh's can opener needs work.

The Michigan coach did the dive at a Michigan pep rally this weekend, as his Wolverines have the week off, and here's the video proof.

OK, so let's break this down a bit.

Harbaugh does an excellent job of grabbing one knee and pulling the leg into his body. That's a crucial part of any can opener dive. The rest of the dive needs a lot of work, but fortunately for Harbaugh, these are fixable mistakes. A little time in the film room and some extra reps will clear things up.

First of all, you need to get the running start, coach. You're on the platform; you have all the space you need. You essentially just fell from it. A running start would have made a huge difference. Second, you need to extend that other leg. Holding the knee was good, but that other leg needs to be straight as an arrow. I see a bend in it. Not good.

Maybe try it without the khakis?

Finally, lean back more! The lean is essential to the splash, as more contact between your body and the water means a bigger bang for your buck. I recommend getting anywhere between a 35 to 40-degree angle on that lean back for the optimal performance.

I hope this helps, Jim.
