Not so fast there. They can keep Noah and Rico, but not Rush. They need to keep Rush over Moore, but they won't keep 3 QB's and risk losing Noah and Rico. 2 of the 3 will make it, and IMO the odd man out is Rush.
So will the other 32 teams really think Rush is better than their back up, unless a team has the luxury to keep a 3rd team UDFA rookie QB?
There is really no reason they can't keep all three. They
need to trim some fat, like Moore, anyway. The problem with keeping all three of these players is it means one of the RB's is likely gone though. Which in the even its McFadden, doesn't really bother me.
With Switzer not being healthy the entire pre-season so far, I wouldn't be surprised if they open up another roster spot for a WR. Rush should/could beat out Moore. Rico has already beat out Swaim, if they're being honest.
Now, will they go with the more talented players and keep these three guys? Garrett's history tells us no. But, there is no reason they
can't.
