Carr was a bit of a reach, I'll admit, but after going back, I'm not sure we've really ever had a player extremely comparable. Brought up Walker because physically they're very similar. About the same height, thin and long. Prohm tried to shoe horn him into being a PG, but last year with TJ he played primarily on the wing and small ball 4. Watson has basically been playing that role just earned his minutes right away and didn't have to wait til halfway thru conference play to get minutes.
I think if he continues to progress, the Ejim and Hogue comparisons could come to fruition, but he is pretty far away from even freshman Ejim, simply due to what the team needed Ejim to be that season. Hogue obviously came in as a juco so was a bit more polished off the bat.
