to expand on kurtz's reply:
the draft is all about perceived value. first round picks are supposed to be better than second round picks, 2nd round picks are supposed to be better than 3rd-round picks, and a guy who was drafted is supposed to be better than someone who wasn't. (i mean, think about it -- would you leave someone out there on draft day if you thought he could be a star?)
of course, when players are drafted often has no relationship to how they'll perform in the pros.
marshall faulk, the rams's stud runner, was the second overall pick (i.e. the 2nd pick in the first round) in '94. he's supposed to be a star, and he is. but Pats QB Tom Brady was picked in the 6th round two years ago, and Rams QB Kurt Warner wasn't even drafted (i think; if he was, he didn't last long in the NFL before getting cut).
The best draft story of all time: Michael Jordan (you've heard of him, right?) was drafted 3rd overall, which means two guys were drafted ahead of him, and two teams wish they could do draft day all over again.
And I'm waiting for that explanation of the offsides rule -- I've watched my share of soccer on the teevee, and I'll be damned if I can figure out what the refs are calling half the time.
