As a freshman and sophomore at Texas, Roach, Coleman, and Jones handled the distribution of the ball, which forced him into usage as a shooting 2G.
So, a couple of questions..
1. Do we have any point guards as good as those three?
2. How much has he grown as a point guard during his redshirt season and preseason practice?
If he hasn't grown his skill set and we have players as good as those three, then we should expect him to again be a reserve role.
If our distributors aren't at that level, and/or his skill set has improved since he left Texas, then it would not be unreasonable to assume he would start here.
