Then why not play all the starters?If they are ready to play, they are ready to play.
A concussion being more likely isn't going to change. He could get another concussion tommorrow or in a week.
As far as posey goes, if he's going to be on the active roster, he needs to take some snaps to start getting back in football shape. If a guy is ready to go it does no good to sit him. If he's not ready to go, then that's on the medical staff. But holding him out if he's healthy and ready is only delaying him getting back to normal.
Why would you risk players that are considered starters in a meaningless game, against players looking to wow their coaches with big hits and big plays, if your plan is to have them contribute in the games that count? Is a few snaps worth it? They couldn't get those in San Diego?
Kubiak is on record for stating that the turf in Dallas is one of the reasons Merci won't play. He's in the same boat as Posey as far as missed TC and PS time. Does that mean Kubiak is relying more on Merci than Hopkins or Posey? I can actually see that regarding Posey, but not Hopkins. Besides, concussions are about eleventythreemillion times more likely to happen than a ruptured Achilles. 1 or 2 more concussions and Hopkins will be a "what might have been". Posey might already be that, considering the nature of his injury. That doesn't mean it needs to be proven in the last preseason game.
Just sayin...
