They are very cautious with these guys and the RTL.
Derek Reese isn't playing at all because of last years injuries, and also he will be playing for Puerto Rico again.
Quinton Chievous isn't playing in the RTL because of an old injury apparently, but he's a full participant in workouts from what I've gathered.
With Maymon I just think its likely an extra precaution. I will really start to worry if September rolls around and team practices start and he's still limited...that's when I'll really worry.
