In certain situations...yes. Not all the time. As stated previously, if Iowa was being pressed they were better off having Connor and Bohannon on the floor together. When Iowa's offense was stagnant it was sometimes beneficial to have Bohannon at the two running off picks rather than Moss. If you watch Iowa with any regularity, you would often know within the first 5 minutes of the game how Moss' night would go. If he hits his first shot, he normally had a pretty decent game. If he comes out and misses a couple, it's normally not a good night for him. That's just how his career went. It's not a small sample size.
I'm not saying Connor is a better all around player than Moss and I haven't said that at all. You know as well as I do that Bohannon is not a pg but often plays the position out of necessity. Bohannon is much more effective running off screens etc looking for his shot. Connor playing more minutes as the season went along had to do more with freeing up Bohannon than anything.
