Overall, a mostly fair analysis -- you made some good observations but speculation may not be your strong suit.
I see little to support your assertion that "Nix is stubborn about his own players (i.e., Davis) and we will suffer the consequences this year" nor is there any evidence they will cut McGee. The Johnny White comment is also a bit off-base. White might not contribute much, but he didn't have much chance out there.
I cannot think of a sane reason why Cincy OR Bills would do that. This scenario assumes the Bengals would only trade for a player worthy of the price, which then indicates that IF said player is worthy of the price the Bengals would win more games, thus taking draft slot out of the #1 (aka Luck) position. No winners in that trade.
Over the last 9-10 games, the Bills have shown they are moving in the right direction. Could have won 8 or more games by now, hopefully next year they'll pull them out and compete for a playoff spot.
He was a 20 year old kid. At that age, you don't always feel like it's entirely your decision (loss of job, ridicule, peer pressure, etc). Kelly et al should have known better to put anyone in that situation. They cannot lose enough.
Getting better each week. One the few shows I watch and rare shows my wife likes as well. Great characters and writing. I like the fact that there's so many unexpected plot surprises but not phony "twists." Great scene when Britt confesses to his girlfriend about how they met. My wife and I now use the line, "Don't judge me."
