I love Kirk Cousins. Not only has he performed well but he seems like an overall great kid. Smart, down to earth, hard worker, great attitude, all that. He's going about this all the right way. And I wouldnt trade him for less than what I would consider a king's ransom. Which to me, at this point, is a first round pick or two second rounders.
That said, if he keeps performing this well in spot starts and in preseason we can't keep him throughout his whole rookie deal. For one, it just doesnt make good business sense. RG3 is the future, and while having a great backup is obviously valuable, especially with Robert's style of play, it's nowhere near as valuable as what you can get for a young, promising QB on the open market. And secondly, it just wouldn't be fair to Kirk. We've clearly sold him on the opportunity he has here to perform well in a backup role to eventually get a chance to start somewhere else down the line (or at the very least he's sold himself on that). Even as good as his attitude is, I can't see him being happy in that role for 4 years, and I don't think I could blame him.
But at least for now, I'm going to be happy with having the best tandem of young QBs in the NFL, without a hint of drama about it in the air.
