There's nothing wrong with Barker. That said, he's a bit of a project in the paint. Some fans feel the scholarship is better spent on trying to bring in an immediate-impact guy. I tend to think that's easier said than done.
But I'm in the camp that feels he's a serviceable big...he could probably put 7 and 5 up in the post if we needed him to, if we have injury problems. I look at him as an insurance policy in the frontcourt, while others view him as wasted space if he's not a threat to see the floor.
I tend to think the latter view is a bit short-sighted, because the same people who want the scholarship to recruit from will be the first to complain about the level of recruitment, or want 3 or 4 of the same types of stretch 4 players, and some of those guys aren't going to see the floor, either because you want 6-7 players at the same generally non-skill-set-specific positions.
Some also think he lacks toughness, which is ridiculous, because he should a bit of fire last year, and his background is in Aussie Rules Football.
But that's where you'll see the different Bradley fans opinions on Barker.
