TSam is playing fine, I don't think anyone is questioning that. He brings a lot to the team. But absent a strong front court, having strong ball handling and shooting by two guards rather than one helps to equalize the front court weakness. At the moment, UConn has a plethora of shooting guards with some, but limited ball handling skills. Ryan Boatright's biggest problem is that he doesn't have another Ryan Boatright on the team. The sad thing is that the media will question his ability to lead the team and ignore how much more responsibility is on his shoulders. To challenge high pressure defenses, someone, possibly Sam Cassel Jr, has to develop as a second premier ball handler or else the front court has to get a lot more dominant.
Having said that, Ollie is an awesome coach and he will guide this team to be the one that no one wants to meet come March and possibly April.
