Some Raider notes:
It appears Trent Richardson is being kept from practice until he gets down to the weight the Raiders want him at. Del Rio said they gave him an ambitious weight goal to get to and he's just not quite there yet.
In the meantime, UDFA Michael Dyer has opened eyes in the first couple days and might make it rough for Richardson to make the team anyways.
Michael Crabtree is getting lots of praise in camp so far with several highlight catches
Amari Cooper has not been as flashy, but is catching everything thrown his way
On the defensive side of the ball, the WR's (especially Cooper and Crabtree) seem to be having their way with the young Raider CB's
Khalil Mack is doing drills mostly with the DL (a few LB coverage drills), and has been mostly unblockable
