Are you referring to how they'll play over the next 10 games... well, that's uncertain for everyone.
In my mind, there is no decision to be made "this season" with respect to these players other than how many snaps they'll be on the field and how many times their number will be called.
I'm fine with the current usage of Austin. Again - it doesn't warrant his contract, but he's still a useful player THIS SEASON.
Quinn is being rotated, and his snap count should depend on his production THIS SEASON.
Watkins, in my opinion, should be getting more opportunities THIS SEASON, but I don't want to force the issue.
I think the potential "problems" will be this OFFseason, when each of these players will be reviewed from a financial standpoint.
