I think they'll both be turnover prone if asked to throw 40+ times for 300-350+ yards similar to the games being mentioned. Most qb's not named Peyton or Brady will be. Since he changed his approach in '09, the only season where he really had a lot of interceptions was 2012.
As far as the here and now, I think Tony will want to play at his usual level. That's just human nature. It will take time to get to that point, if he can reach it. We'll see.
My suggesion to Garrett is to just cut out the middle man, put in an extra blocker, and direct snap the ball to Zeke on the first play every game. That way, when asked "the question", he can accurately say "neither!" And then Zeke can say "It's *my* team now, ******s.
