OK, I'll do the work:
Big 10 games 24-70 30% shooting
* I don't know your history on the Big 10, but lots of cyclone fans call the Big 10 the worst conference in basketball and football
Wisconsin (2 games) 1-9
Maryland (2 games) 1-4
Michigan (2 games) 3-4
Iowa (1game) 1-6
Nebraska (2 games) 3-9
Purdue (2 games) 7-14
Rutgers (2 games) 4-9
Indiana (1 game) 2-5
illinois (2 games) 1-8
MSU (1 game) 0-2
Northwestern (1 game) 2-5
Minnesota (2 games) 0-2
OSU (1 game) 2-5
Non Big 10 Games 28-74 38%:
Non P5 Games 21-45 47%
P5 Games 7-29 24%
The teams you play against very much matter, so the number of 3 pointers you make must have some context if you are playing in a P5 conference.
I don't have an axe to grind with bolton, but he is not a good 3 point shooter. He is below average at best.
