As good as any but better than most
You criticized Vaark earlier for attacking your post because it was a different opinion than yours. Now, you call someone a retard for having a different opinion than yours. Hypocrite much?
Also, can you really say with a straight face that the mistakes Sparano makes are similar to the ones that Belichick makes? Is Belichick constantly outcoached in the second half of games like Sparano is? We must be watching two different NFLs.
For every team you mentioned that has stayed consistent with their coaches, I can name a team that improved after firing their coaches for another.
