I wouldn't say light years - TJ has more than held his own on offense. He obviously can't create like Parker, but his 3-point shot has been pretty consistent for a couple seasons now, and we all know he's an asset in transition.
These two guys are asked to play different roles on the court, I'm not really sure why they're being compared. TJ comes in to replace Pickett/when the bigs are in foul trouble, and Parker was able to get a couple buckets while both Jimerson and Perkins were on the bench.
I really wanted that transition 3 from Yuri to Parker to fall late.. we were feeling it then. I've been really impressed with Parker and could easily see him average 15 ppg before his time is done at SLU.
