No point in trading for Cousins, there's almost no chance he succeeds. 0 WRs and TEs to throw it to, so it would just be a waste of his prime years. If Shanahan reealllly wants him, wait until next year since he seems to have a rift with the Redskins. Besides, next year's quarterback class is much better if they fail to sign Cousins in FA.
I don't agree on a lot. They have so many cuts on the OL you didn't mention including Dunlap and Franklin which will save them 12+ million. Stuckey is not worth 3 million. They can make on very solid move or a couple with draft help to protect Phillip. Cruz could be an interesting pair with Allen if he can return to prior form though.
