K.C. Johnson posted a very short article a few days ago wherein he mentions that Thibs went to Rose's workouts in LA recently. He doesn't have any new quotes (one from July), but he did pique my interest with this tidbit:
Thibodeau traveled west Wednesday to check in on Rose, who is sporting increased range on his jumper and a left-handed floater that he has worked on extensively this offseason.
We all knew his jumper would be better, but this is the first I've heard of Rose's new left-handed floater. He's always been good at finishing around the rim with either hand, so this is probably just him expanding his toolbox. It can't be a bad thing if his lefty floater is consistent, although I don't see it significantly changing his game next year.
