Besides, if there's someone you just got to have in the top 10 (or in the first round say for instance) you can always bundle the rest of your draft picks together and trade your way on up there.
Which IMO is saying that you go jump on someone in the top 10 because you're absolutely, positively certain that this kid is what you're missing. It's like signing a really, really expensive free agent. You go get him when that's the exact piece you're missing. Otherwise if you don't have to be in the top 10 then don't be. I'd much rather watch wins than the draft (though come draft day I'm so hard up for anything football related that the draft ain't bad)
