I was very sick of Cowher, starting during the Kordell years. He did blow coaching during home AFCC games, three times. (SD, Denver, NE). Belichick typically plowed the field with him. And when MT came on the scene, I loved him; I felt that he always said the right things. But as time wore on, most of us noticed his rhetoric was mostly empty. And while BC was becoming infamous for being stubborn on pulling players (thus admitting being wrong, and keeping ****** players like Kordell, Scott, Gildon, Washington, etc.) MT is much more flawed in this area. His insistence on keeping Blake on the field is beyond imbecilic.
Likewise, I hated the fact that Cowher never brought anybody to compete with Kordell, although some people say that there weren´t enough good enough QB prospects during that time. I personally didn´t buy that. Also I couldn´t understand why Scott and Washington lasted so long as starting CBs.
However, to be fair, Cowher was very good at rebuilding his teams, despite the exodus of good players we used to see leave to free agency every year.
