I agree with everything you said, except I don't think Gates needs mention. He's still a top tight end. 4th in PPT last year with Gronk coming in 3rd. 5th in catches last year among all tight ends. He might not be who he was in his prime but that goes for every football player. He's still solid as they come. I'd talk about the running game for the chargers not being elite before even mentioning Gates. The Chargers need to run the ball better. The offensive line for the Chargers is definitely the biggest cause for concern. As far as quarterbacks go, it's really hard to talk about Philip River's lack of mobility/being sack prone after watching Vick's last game. Vick didn't have a clue last weekend and threw for 100 some odd yards. He looked like a rookie last game. I'd take Rivers over Vick in a heartbeat.
I wouldn't be surprised to see your money line cash. The Steelers have a lot of potential and if Vick can get it together, I think your bet is pretty good because I feel that either Vick shows up to play and Steelers pull the upset or he's the same old story and chargers take off with this game at home. BOL buddy!!!
