"Unripe developmental guy with decent tools and football IQ that's been bitten with knee injuries and struggles off platform."
Strengths:
Strong armed, precision passer with functional mobility. Flashes strong ball placement out of a clean pocket. Poised and gets to his second read quickly. Flashes good anticipation. Solid linear running ability if it's there. Upside.
Weaknesses:
Can't improvise or buy time effectively. Off platform throws are a struggle. Too mechanical. Accuracy glitches occasionally. Questionable decision making at times. Lacks experience. (11 career starts). Multiple left knee surgeries.
Overall:
Mills has accuracy and decision making glitches on film that are common to a QB that's only had about one season's worth of meaningful starts. He's a guy that almost certainly would have raised his stock by remaining at Stanford.
Which raises the elephant...why did he declare and what truly motivates him? As it is, he's a developmental guy with decent tools and football IQ that's got potential medical red flags after injuring his left knee twice, requiring surgery each time.
