With all due respect, I fail to see how playing at Syracuse is better for his development than is having unlimited practice time, access to professional coaches, and access to the best competition in the world. The only area Syracuse trumps the NBA as far as development goes is probably playing time (albeit against far inferior competition). As SeattleCuse said, it's up to Fab really how hard he works to improve outside the games. From what I've seen, work ethic isn't a problem. You dont drop 30-40 lbs in one offseason without dedication. I also don't really buy that he's going to magically jump 1 round by coming back. That tends to not be how this process works. Especially with respect to big men, potential is what you're drafted on, and perceived potential only declines with age. Coming back 1 season and showing improvement but not showing the "expected improvement" actually hurts you. See Kyle Singler, Josh McRoberts, etc. Probably would be better off with that guaranteed first deal.
