They were the tamest "shots" he could possibly take, and ultimately I think he was just saying what most people say in that position about winning (the Bears were an awful team the entire time he was here) and how it's nice to be appreciated (paid). Feeling any kind of slight here is ridiculous to me but whatever. It literally does not matter.
And I'm not even a Monty fan, I agree and have the entire time 100% with letting him go, etc.
