I see your point about Jefferson, and it's a good one in general. Nice to have Jefferson's defensive versatility among the Bigs. However, my bigger point was a concern about us continuing our hard trap defense. We love to trap the corner (coffin corner) and for good reason, right, and we also hard trap different teams at different places on the court depending on their personnel. It's worked well and in general, I've been so impressed with TJ and staff. For example, we were trapping the outer thirds of the court it seemed like a fair amount against Houston. We disrupted their offense a bit and they kind of settled into just iso ball and let Cryer (mostly) or Uzan just go one-on-one to try and get a shot down the stretch. That's a testament to our defense. With BYU, their players are good at ball movement and good shooters who like to space it, probably better than UH in my opinion, so I don't know if that strategy will work against them.
I don't think the switching is as important - its whether we continue our hard trap defense and they beat it creating a 4 on 3 on the other side and a free three pointer for one of their shooters. That was deadly against us last year. Again, will be interesting to see what our staff draws up. It's fun to watch us play D.
