Cheypoke has it right, this was one of our biggest problems the last few years. I can't count the number of times I found myself yelling "Catch the damn ball!" since Glenn got here. Probably half of the interceptions we had last year were a result of the ball bouncing up off a receiver's hands. Our QB's recently have generally put the ball in a catchable position, but receiver's weren't doing their job. If Glenn and company had recruited some receivers that could spread the field and keep the defense honest, the run first plan might have actually worked.
While I think it was a recruiting problem to some extent, I think it is a teachable skill as well. You can teach a kid to catch the ball, and train him to be tough enough to sacrifice for it. And at the vary least, you can teach them that if you don't catch the ball, knock the damn thing down. I'm sure that DC and company are spending a lot of time on it, but it definitely has to be fixed. We may be looking at some freshman that aren't as developed but can catch the ball. it's got to be a priority for recruiting as well.
GO POKES!
