I'll assume you mean Shanahan as #2 best coach...you have Sherman listed in both.
I would stick Belichick in over Saban...that NE team was a mess halfway through the year and is now Division champ and looking very good going into the playoffs. Saban is honorable mention for sure, though. I like seeing Smith, Lewis, and Dungy in the top list.
Capers is obviously the worst...one could make a case to put Norv Turner and certainly Mariucci/Jauron in there over Sherman and yes, even Tice. Heck, I'm not even so sure Haslett is all that bad for this particular year. They went through a lot of crap with the hurricane, lost their RB, lost their stadium, got screwed on a couple of questionable calls, etc. I just don't see it all as his fault. Any time you lose one of your key pieces I really don't see you as a bad coach. But yes, in general he's not very good.
My bottom 5 would be Capers, Mariucci/Jauron, Mularkey, Turner, and then maybe Sherman.
