How so? 13-6 is 13-6. And yes they did miss the playoffs without Tommy, but they did go 11-5. That doesn't happen very often.
Think about it, Bill Bellyache and the culture of cheat are 13-6 with Cassell, Garapalo, and Brisket. When Tommy leaves, if Bill Bellyache stays, they'll plug in the next man up and roll on.
We only play 2 games a year vs them. We could go 14-2 and win the division if our problem not making the playoffs rested on Tommy's shoulders alone.
We've split with them a few times but still lost to the Fish and Jets twice (last year) and a bad Raiders team (2015). That's why we're not making the playoffs.
