I came in here to say the same thing. They shud rest now for sure. I think Harris is already resting.
I think this should boost his confidence as opposed to what you mentioned. It should give him a feeling that the HC trusts his abilities and do not want him to get hurt so he can start the playoff game.
True I just want to see him succeed through a whole game though against the D he will be playing against next week. Going a whole game with a td and no picks should keep him confident and pumped for saturday.
