Hopefully Sam is finally healthy. But I think what we're seeing is what he's capable of. He looks athletically challenged at this level. He also seems to try to do too much instead of playing more like a role player in getting the ball to others on the floor. If he can come in and hold his own on both ends of the floor and not be the player responsible for a bunch of empty trips resulting from him missing a bunch of shots, he might get a few minutes here and there to help keep the backcourt fresh for the stretch run at the end of each game. The with the depth at the guard position now, PT will be very hard to find for him.
As for Facey, it looks like he'll be battling for front court reserved minutes with Phil, and I see him winning that battle if he can come in and play with energy and efficiency. He showed some nice skills, but tends to be passive. If he can come in and play aggressively though under control, he'll get his minutes. As pointed out, he struggles on the defensive end at times. He needs to play with aggression and energy to make up for his lack of strength. He's one of those players that could blow up and have a good late-career like Donny Marshall, or have a unremarkable career like some of those bigs whose names I can't remember...because of the obvious.
What will likely affect his minutes most, is KO's flexibility to put Hamilton at the 4, and use many different 3 guard combinations. I'm one who's always an advocate to put your best five players on the floor, and unfortunately in most cases Facey isn't one of them.
