if you draft a rookie. maybe. but you are paying a 4th for a QB that has lots of deficiencies and is not a legit NFL QB. essentially you paid a 4th for a back up QB. and the only reason we paid that 4th was because of his draft status being a top 3 pick. otherwise nobody would pay that. rumors were that Bills were interested but for a 6th!
what will happen is he will have opportunity to sign with any of the 32 teams. if somebody is stupid enough to give him a better offer, why stay in Dallas? and if we think he is a good QB, worth the 4th rounder, why not pick up his 5th year option?
