Yeah I think there are a couple reasons why that sort of thing is tough for us.. Teams know who we are at what we have to do to win games, which is shoot it well from beyond the arc.
Before Tyrese got hurt, we'd run Tyrese off tons of different screens (curls, flairs, etc) and then let him play off of it with the screen man. I think sometimes we did fall too much in love with that and at the time Tyrese was playing guys weren't shooting the ball well either, so it wasn't effective at times. With the guys we have though, I wouldn't want them running a ton of those types of screens because I don't want them getting the ball where the trees are and shooting floaters all day long because they can't finish at the rim.
It also didn't help this year that we were playing half of our conference games against some of the best defenses in the entire country. KU, BU, and WVU are all in the top 4, TTU is #11, and OU is #25. Those teams can flat out guard.
