I find it wild the Cards, after burning up so much capital last year to get Rosen, are now hooking him out the building.
If I was them I would trade first pick for a couple of Raiders first rounders, trade out their CB who is agitating (always forget his name) again for a 1st and probably a 2nd or 3rd then rebuild around Rosen.
Take 2 new Lineman from the first round and possibly a TE then use the second rounders for the D. They could go forward with a good young core and make relatively quick progress. Ditching Rosen and going to Murray still leaves them with huge issues across the team and will probably just see Murray get a season of the same treatment Rosen did then written off as well.
What will happen is though is they will take Murray, get rid of Rosen and be lucky if they get a third (which is ****** up) and then be the same shambles they were last year.
