I guess any player who performs horribly is subject to being replaced in the lineup and TS is no exception. However, I can't say it would be based on any one thing, such as INTs which require the R making a clean catch, the OL providing protection and of course, the R being where he's supposed to be when the ball gets there.

TS had only 10 INT's in 2016 playing behind one of the worst OLs in the NFL, a nonexistent run game, poor starting field position from ST returns and a level 5 shoulder separation. Nothing in the past 3 seasons points to TS having horrible showings against "mediocre teams" and IMO, the Cows are NOT mediocre w/wo Zeke (interestingly, I've read that the Broncos face the toughest scedule in the NFL this year).

Trevor can't undo any "anger/animosity" caused by factors he had nothing to do with, so why he would be made the object of retribution for the team failing to win seems unreasonable. OTOH, TS can do a lot to sooth those feelings by winning, my expectation.
