MSU has three road conference wins by 10 or more. They won other games in conference by 29, 30, 28 and 30 points respectively.
So they comfortably won about half of their conference wins. Lots of close ones, yes but any road win to me is a good one.
If the assumption is that this team hasn’t played close to their full potential yet, then that’s a scary thought to me.
As @umhoops mentioned, a team that can space them out is the bad matchup. Or any team with a guard that will feast on Winston one on one. Villanova, Oklahoma, Kansas come to mind. But in general, I just don’t agree with the sentiment that a 28-3 (16-2) MSU team with zero bad losses has been unimpressive.
