I'm surrounded by Stiller fans too, and there are two segments of the fan base. Three, I suppose. There's a small segment of blind Tomlin loyalists. There's a very vocal minority that think he's overrated or JAG at coach. Most of the fans around here seem to think he's pretty damn good and an important cog in (what has been) a great organization. With Colbert's retirement, and the younger players, the culture might erode. Then again, look at what he did with Antonio Brown. Everyone thought he was too indulgent, babied him too much, etc. Sure, he had behavior problems in Pittsburgh, but he exploded after he left. Tomlin got a lot of credit after that.
Is he the perfect coach? No. But to go that long without a losing season, regardless of how good your organization is, is astounding.
