They are three different types of guards (Burton a physical 6'4 CG with an improving shot, Wertz a smooth 6'4 scorer/ballhandler, Walker a prototypical 6'2 PG who is improving his facilitation) but stats-wise their overall quality is comparable--last season averages, efficiency, A:TO, all roughly in the same ballpark as far as offensive guard play is concerned. So then I look at their physical attributes and level of competition they played in college and who I think would fit best at OSU and in the B1G. By which measure I am going Burton 1st, Wertz a close 2nd, and Walker a couple paces back at 3rd.
I would be pretty happy if we landed any of the 3, but with Walker I would have the biggest question mark about how much his game would translate to this level. Both Burton and Wertz have a bonus, too, where they were plus rebounders at their former schools. I think what gives Burton the edge for me is that he is easily the best defender of the three and he played the best comp while on a solid team and has been coached well. Also, the way Burton improved his shot from his frosh to soph seasons from 30 to 40% even as the line moved out more... it shows he has the work ethic and potential to be a phenomenal two-way player--not to mention good size, length, strength, and athleticism for a college guard.
