I think he's one of the best value starting QB's out there. He's not a "high profile" player, so a lot of guys just don't bother to think about him. Just like last year, I would love it if I could grab this guy in the 5th or 6th round...underrated due to his INT's, but his yards and TD's more than make up for it. He very rarely has a bad performance. The receivers are getting older, but as long as the Martz style of offense is there, WR's are going to be there to throw to.
I don't know about top three, but he should be in the top 6 for sure as far as performance. Like I said, if you can get Bulger in the 5th round, and you combine him with a top notch RB/WR in the first two rounds and some good producers in round 3 and 4, you will have a very good nucleus to work with.
