Always a possibility, but I doubt it. I don't think he was ever really going to play this season, especially with the start we had. I believe Ballard is looking at the big picture instead of the immediate that the coaches, players, and most fans do.
With the roster we have, there was no way we were making the playoffs, so no need to rush back your star QB, but you need to sell tickets, so you keep him on the roster and keep the news very vague about his status. People still buy tickets in hopes of seeing Luck later in the season, when in reality, they're going to see a bad team, most likely lose.
In the process, you end up showing off your backup QB that has played incredibly given the circumstances. Not only will we most likely end up with a top 5 pick, but we could also flip Brissett for a pick or 2 in the offseason. We enter the draft with a handful of top picks to add to the seemingly strong draft this year, as well as great FA group (Simon, Hankins, Woods). Ballard is masterfully setting us up to be successful for the long haul, not making the same mistake Grigson did and try to win now.
