CJ is replaced by Myles Johnson and potentially another Big....
Nigel is replaced by Geo Baker
Corey is not someone you immediately replace, but my guess (a pretty good one almost all the time) is that you have an available spot on a B1G roster and you become immediately more attractive to some recruits....it doesn't take an all conference player to make up the difference.
On FT shooting alone, an 80% FT shooter that is a normal 8PPG player, can get to 12PPG if that person gets to the FT and converts FT's.....Sanders PPG average if he's a better FT shooter is probably 4 to 5 point per game better if his FT shooting was around 75% to 80% vs hovering below 60%....
There are so many ways to add scoring without having to do significantly more offensively....the sets and game plans designed put RU in games, they didn't belong in some nights and FT shooting more than anything derailed what could have been an even better season.
I have no idea how the team will shoot next year from the line, but if Baker is at least respectable (70% or better), there is no dropoff vs what Nigel Johnson provided offensively....Baker is a better shooter, more athletic and longer armed defender....Nigel was a better on the ball-defender, but it's not as if Baker can't learn how to defend.
The kid McIntosh from Northwestern is a step slower offensively and two steps slower defensively vs Sanders....McIntosh however understands the game, angles, how to create space to shoot and draws contact to make FT's, something that can be added to the game of Sanders.
RU is not dropping below 10 wins if Sanders leaves....there will be comparable replacement if that happens and everyone on the roster has a chance to step their games up and score....
