No way this is just a rumor IMO. There is just way too much smoke; way too much. Only confusing part is that there is this much smoke to begin with. You figure without a HC, there would be a little less noise regarding TT and whether or not he'll stay/go. The fact that it appears a given, tell me one of the of following:
1. The Bills have made up their minds that they're not bringing TT back, regardless of who they hire at HC, and therefore any/all interviews are based on what the HC will do with the team without TT. The candidate is made aware that TT is not part of the picture during the interview.
2. The Bills know they'll hire Lynn and Lynn has either made it known he's OK without TT or that he'll accept whatever the Bills decide to do with TT (which is let him go).
It has to be one of the two. If all these reports end up being false and the Bills keep TT, it'll be one of the biggest gaffs in recent memory by media/reporters.
