Why not let him go before this season when you decided he not only wasn't good enough to start but that he wasn't good enough to even be a backup or even be a QB for that matter?
Two reasons: Daniel Snyder & Bruce Allen.
Kirk & colt were mediocre in training camp & OTA's and rob had his struggles but was ok. After the lions preseason game, gruden used rob's concussion & mccloughan to convince synder that kirk was the go to guy for the season.
Snyder wasnt convinced & didnt wanna give up on robert because the kid is only 25, very smart & has a LOT of upside.
So far gruden is underachieving with a 8-17 coaching record & cousins has been inconsistent. Kirk hasnt convinced the FO that he is the guy going forward even though gruden wants him to be.
If we end up going like 4-12, i think its a strong possibility gruden is fired and anything can happen. Its not a foregone conclusion rob is done in DC because synder really loves him.
Also rob is under contract next year, kirk isnt. Kirk has the ENTIRE local DC media on his side, the HC & the GM. If he fails, its his fault, personally I think his ceiling is a back up. Funny how so many skins fan call the read option stupid but cam just put 5 TD's on us with it. Its the redskins, anything is possible because they're the epitome of dysfunctional.
