I don't agree with the idea of "well, if he can play let him play." This team is in a unique situation to already be considering implications for December and January. They have to play the long game. If Peters is already "day to day" then he likely has a good chance to play in week 5- and beyond. And their approach with him and decision becomes
exponentially more important with Talib out.
You can survive without two starting CBs for a game when you have Shields, NRC and an elite DL
and you're playing at home on a short week. You cannot win without two starting CBs for 8-10 weeks... They should absolutely err on the side of caution with Peters here. In the longer run they need him to face #1 WRs when they go up against Rodgers, Brees, KC, etc. Give the guy- who couldn't put weight on his leg 3 days ago- a little time here to get right...
