So about this (I assume we're talking about the AP NFL CotY): unless you think 8-8 wins the AFCE, this would be lighting your money on fire as iirc every AP CotY for the last 20 years has been a division winner. Belichick has won the title three times, second to only Don Shula with 4.
If you're a Bills fan, McDermott CotY+ BUF AFCE champs is a no brainer parlay. I'd spread some out on other likely division winners...just for value's sake I like Gruden +4000, McVay +2800, Tomlin +2800. Hate Stefanski because as mentioned I don't think Browns are close to winning their division, Reich, Flores
