As for missing 49ers, not a huge deal, but QB 4 Nick Mullens(Practice squader last year), SS Don Jones(probably in FA pool, was on IR last year), LB 49 Boseko Lokombo(Practice Squader last year), and 2 other LBs, Jimmie Gilbert which would be with Eli Harold, Watson LBs, and then Donavin Newsom, either MLB or with Malcom Smith.
