I think you're partly right, but I think you're overestimating it a bit. Lynn doesn't coach defense, and it's really up to John Pagano to stop the opposing offense. Lynn obviously knows Taylor, but that only goes so far. Moreover, a lot of other coaches "know" him pretty well at this point. Todd Bowles had faced him five times going into the Jets game.
The Bills desperately need to win this game. Don't rule anything out.
