what are the bills and saints supposed to do, not pay their franchise LT's, which you have stated in the past are one of the 3 most important position on a team? They are both elite and at the top of their game, while still young. Don't see any reason why they shouldn't be A grades.
Summary: Barton is an extremely gifted scorer when attacking the basket, and his length serves him well defensively and on the glass. However, at 170 pounds, handling the physicality of the pro game is his biggest obstacle in transitioning to the NBA. Because of that concern, he will likely be a late first/early second-round selection.
Player Comparison: Corey Brewer. Like Brewer, Barton is a long, athletic, slashing wing who entered the league needing to add muscle to thin skinny frames. Neither guy shoots the ball efficiently from the outside, but both excel in the open floor.
