I don't think Dak is looking over his shoulder, nor do I think Milton could challenge him for the starting QB position. But, I also don't think Dak will make it through this season without being injured. Dak's body is starting to fail him just like Romo's body did to him. The real question is, when Dak gets hurt, will we see Grier or Milton? I've seen Grier play, I'd like to see what Milton could do if given the chance over the span of a few games. One thing is for sure: Milton presents the only real dual-threat QB on the team.
