Steve Spagnuolo (Jets, Broncos) and Kevin Gilbride (Raiders) both had interviews Saturday for head coaching jobs. Adam Schefter of NFL.com speculates that the Giants would be willing to make Spagnuolo 'head coach in waiting' to keep him.
I don't think that's a good idea. I think that's somewhat disrespectful to Tom Coughlin, since it tells him he is done at the end of this contract. Also, as secure as TC is, it still changes the relationship between Coughlin and Spagnuolo, and potentially splits locker room loyalty.
As much as I don't want to lose Spags, I think 'head coach in waiting' would be a mistake.
