I'm with you on the Vikings and Dolphins, but I'm not sure about your read on the Giants. They're not getting healthy. Their two best O-linemen (Pugh and Richburg) are doubtful. With a decimated O-line and Hankins out, the Giants are clearly the weaker team in the trenches in this matchup. You mentioned that the G-Men could be motivated by their opportunity to cushion their lead in the NFC East, but don't forget that Washington can pull into a tie for first with a win. Just some food for thought.
1. Hackenberg needs to the right team with a mature environment where he can sit behind a quality starter. He is the best arm talent in the draft. Has excellent footwork and a nice release. He moves well in the pocket despite all the sacks. he is a play action quarterback who inexplicably plays zone read in college. In the rare instances they run play action from under center he looks great. Then they go back to zone read. The defenses don't honor his running ability and just tee off on the running back. Which puts them behind the chains consistently and there is no draftable talent offensively on his team outside of the RB Barkley(freshman)
Summary: Cameron Newton became a superstar in a very short period of time. His circuitous route to the Heisman trophy and BCS national championship will be scrutinized by NFL decision-makers. Whether or not he actually knew about his father auctioning his services to the highest bidder, there are other red flags in the character department for him to answer to. Lack of big time college football experience is a huge concern. FBS teams barely had any time to assess his weaknesses and attempt to exploit them, something which is not going to be the case at the NFL level.
Player Comparison: None. There is no single player Newton's game compares to. His combination of size and speed is pretty much unprecedented. The laziest comparison is Vince Young and from a scrambling standpoint it is fair, but Newton is more accurate as a passer. He is not going to give defensive coordinators ulcers preparing for his running like Michael Vick has, however, which is what makes him such a unique prospect. Dream scenario is that he is a faster Ben Roethlisberger.
