I think Chilly getting Gus' input is a great idea. Fran Tarkenton once said that it is absolutely essential that a QB believe that the play being called can get the TD or
get the 1st down or do SOMETHING. If he doesn't, the play is almost certain to fail. If Gus is skeptical about a certain play it is correct that he should bring this up to Chilly and Chilly should listen.
