Last year the field goal percentage from 2-point range averaged 50.4% for all Div 1 teams. The 3-point FG percentage average for all teams was 35.2%.
There were 265 NCAA Div 1 teams that shot 33.3% or better from three point range. So from a strict statistical standpoint it looks like the 3 pt. shot wins over a 2 pt. shot but as we all know that doesn't tell the whole story. The numbers are extremely close and teams will really need to figure out their own strengths and weaknesses. I do believe it makes a lot of sense to do a statistical analysis of your team and base your style of play to some extent on that analysis. It would make sense that a team with strong 3 pt. shooters would play a different game than teams who play "big" inside and play well at the free throw line.
