Let's hope not. Not only do I feel like this would be bad a bad move for the team. I also think it might start hurting them in the fan engagement/interest department. Starting JB with a highly drafted QB is a strategy even non-JB supporters can probably get on board with; going into the season with JB as your unquestioned starter and no back up plan might cost them ticket sales, viewers, merchandise sales, etc.
Perhaps, but you watch, they'll take their time investigating, wait to see if New England makes it thru the playoffs and then take action. Of course, by then, Ms Brady retires, the Hooded one as well and McDaniels is left to deal with all the aftermath, that would actually be hilarious to some degree.
