Williams is a very solid big (in general) for Pope going into his fifth year. Not really a shooter, or passer. Not sure it's a great fit for how Pope ran things offensively at BYU, but maybe he surprises as a shooter, and passer.
Carr, on the other hand, seems like a very good fit for Pope's offense as a stretch four as a fifth year. Not a great passer either though.
Oweh is a good transfer as a junior but he isn't really a volume shooter from three, so it will be interesting to see if his percentages can maintain with more attempts under Pope's offense. His assist rate is pretty bad so far.
Chandler is a freshman so who knows, but he probably fits Pope's offense the best considering he was recruited to BYU.
Butler is a good defender but in four years at SDSU he has been a mediocre shooter. His A/TO rate is good but how he only averaged 3 assists per game is really not a good thing.
Of the four transfers, they all need a lesson in ball movement especially with how Pope coached offense at BYU. They also have Travis Perry who is the sole Cal recruit to stick (Kentucky high school player).
Overall those transfers don't seem to be great fits for Pope's offense (which was predicated on ball movement, screening and three point shooting) aside from Carr, but should improve his defensive schemes just by being more athletic.
