That is probably more significant in creating a disparity in the number of FT attempts.
There are a maximum of three 1-and-1's called in each half, potentially on the 7th, 8th, and 9th foul. But the 1-and-1 is not called if the 7/8/9 foul is a shooting foul, technical foul, or player control foul. So while it is possible for a total of 6 1-and-1's to be called each game, I would guess the a whole lot less are actually called. I looked at our recent games vs Pitt, MSU, Wisc, and SH, and Rutgers had a total of 2 1-and-1's called in each game. Even if we missed the front end of both 1-and-1's each game (we didn't), that means we only lost 2 FT attempts per game.
