First thing - let us have some fun. After the prior 5 years it’s nice to have positive speculation for the team on this board.
IMO, there are two huge benefits to Philo’s performance this year. First, he’s adding serious competition to the QB room, which is only going to make everyone work harder to get better. Huge benefit. The second is that it gives us optionally for game planning next year. You say that if King is healthy we won’t see much of Philo next year, but my guess is that he will play a good bit even if King is back and healthy. He’s too valuable to keep off the field with his deep ball ability, and there will be certain opponents where it may make sense for him to take more snaps.
Anyway, that is pure speculation, but all I know is that the starting role isn’t going to be handed to King next year, he’ll have to keep working and improving to earn it. And it’s great to know we have 3 experienced and game proven QBs.
