It's a debate that rages about this time every year: Should a team draft for need or take the best player available?
A number of clubs will be making that decision when the NFL draft begins at noon today on ESPN.
Oakland, Detroit and Cleveland have the top three picks, barring trades. All three teams need quarterbacks, and LSU's JaMarcus Russell and Notre Dame's Brady Quinn will be available for two of them. But most NFL scouts and draftniks rate Georgia Tech wide receiver Calvin Johnson as the best player in the draft, with Oklahoma running back Adrian Peterson not far behind.
If either Johnson, Peterson or Quinn slides down the board, can a team that covets a different player bypass any of them?
The "best player available" theory prevails for most teams, for a simple reason: Pick a guy to fill a hole now who's not as talented as you'd like, and you'll just be replacing him eventually anyway.
"I take the best player because at the end of the day, what's my worst case scenario? I've got a lot of good players," said Charles Davis, a draft analyst for NFL Network. "If I'm saying I've got to have a left guard and the highest rated left guard on the board is really a third- or fourthround guy and I'm picking him in the second, I'm reaching. Am I really helping my team by taking a guy I could get two rounds later and wasting a chance to get another great player? I don't think so."
Davis said he would have no problem drafting the highest-rated player on the board even for a team that was well stocked at the same position.
Not everyone shares this opinion.
"I believe in taking the best player, but you can't draft a player you don't need," said ESPN draft guru Mel Kiper Jr. "If you have a ton of money spent at linebacker, you can't draft a linebacker. You're drafting the best available player at a position of need in the NFL right now."
Whether teams want to fill a need or take the best player, this draft provides an opportunity to do both. While the class lacks the star power of last year, there is plenty of talent to go around. Here's a position-by-position look at the draft prospects:
JaMarcus Russell, LSU, 6-foot-5, 256: A big, mature signal caller with good mobility and tremendous arm strength that allows him to deliver high-velocity throws with a mere flick of his wrist. With more polish he has the potential to become an elite starter.
