I don't think you can really teach how to catch either. You just can, or you can't (I never could consistently myself). And if he hasn't figured it out after this long, the odds are really working against him. I hope you're right though, of course.
My pick for who is supposed to be really good, but won't end up being that good: Our LB corp. They just haven't shown me anything over the last couple of seasons that makes me all that confident in them. I do really like Kirksey and think he'll be solid, but I still see Morris getting caught up in traffic and Hitchens bad tackling form continuing (hope I'm way off on this, of course).
My darkhorse pick: Canzeri. The guy looks real cut now so he'll be able to shed first contact a lot easier, and he's got the wheels.
