January or February of this year is better measuring stick.
As Grizz stated, the rookie year included a good deal of time (and pretty much all of training camp) with the calf injury. When he got healthy, he appeared okay, but lost.
Last year, he was inconsistent. I can only hope that it's because of the lockout. Comfort in Pop's system doesn't come easily. Maybe a full training camp, some time with Chip and extensive time just talking with the coaches over the summer will help.
His pseudo-ceiling is good starter, above average bench 5. He's a guy that needs to be good, not great. Just don't be a guy who teams exploit.
Come March-June, we'll know for sure. No need to brand the guy just yet.
