You could argue with the validity of this cowardly remark about Callahan, a candidate for the Jets head coaching job.
As a rookie head coach, he led the Raiders to the Super Bowl where they lost to Tampa Bay. In his second year, the Raiders struggled, and he was fired after getting sabotaged by some veteran players like Charles Woodson and Tim Brown. Callahan thought the team was getting old, and started a youth movement, and that didn't sit well with the veteran players, and they complained to Al Davis, who fired the coach.
Not exactly an example of running a team into the ground. It was more a case of Davis not having his coaches back.
And then he went to Nebraska in 2004, where they were 5-6 his first season. Then he was 8-5 and 9-5 his next two seasons, and went to a pair of Bowls.
Then in 2007, the Cornhuskers finished a disappointing 5-7 and he was fired.
Once again, not an example of a coach running a program into the ground, especially since new coach Bo Bolini took the players Callahan recruited and went to a Bowl game this year.
So this disparaging remark from the unnamed assistant was clearly unnecessary and inaccurate.
While Callahan is clearly a long-shot for the Jets job, if he did land the position, it wouldn't be a bad choice. The man has an excellent football mind, and is one of the best offensive line coaches the Jets have ever had.
