The Raiders chose him at number one, enough said. And the next best QB in the draft was Brady Quinn, so it's not like the there was a lot out there to choose from. Coaching and supporting cast made Jamarcus what he was at LSU. He was an arm talent with the size that made it hard to bring him down. An elite QB is a field general who can read a defense, look off safeties, throw guys open with anticipation skills. Someone who has great work ethic and makes players around him better not the other way around.
I read an article where he says he was getting loaded with Lil Wayne before Raider games. Makes you wonder what he was doing while at LSU. He didn't just start drinking syrup and getting fucked up when he turned pro, I mean I guess there is a possibility, by seems unlikely.
I saw the video with Lil Wayne and 2 Chains where 2 chains said JR brought a bag full of codine and was handing it out and spiking drinks at a party. And I agree that didn't just start after he got drafted.
