If Taylor is playing well, he should get the full season.
If his play slips, I wouldn't be quick to pull him out. It all depends on how well Mayfield is showing in practices. A lot of Browns fans are always looking for the rookie to play immediately. We have to wait for them to show they're ready, or they struggle and get written off(by fans and the org). As you said, though, if Mayfield is killing it then he has earned the right to go out there. I just don't want to hear fans booing Taylor and calling for Mayfield if he isn't ready to play(ala Manziel). We need to support whoever the coaches determine is the best player
