Because he was drafted as a development QB, showed promise in half of his preseason appearances, did not **** the bed like EJ did in final game last year, has only taken 11 snaps in regular season games so far. Is very athletic/mobile to fit a Bills O-line that is poor at pass blocking, can handle windy bad weather games because he has a cannon.....
If that is how a team develops a project QB they are all dumb asses at One Bills Drive.
If CJ is cut then using that same Bills project strategy: If Bills had drafted Dak then he would have never been given a chance and then cut this year.
