Thomas, Nelson, Henderson and Smith are all great athletes! I bet Henderson and Nelson see more PT than any of those guys but Paulus anyway.
For all the crap McClure gets for being unathletic, he is probably the best defender on the team. He is gritty, and has great energy. If he's healthy, he's a superb role player/glue guy.
Scheyer will, hopefully, be a 6th man. Despite late season struggles, he was our most efficient offensive player last year and is a definite asset with a year of experience.
But I agree that we really should not have to play Paulus and Scheyer together much. Together they are a bit of a defensive liability - if just 1 is on the floor, we can be ok covering for them. Hey, they are both already better defenders than JJ was in any of his 4 years.
