I would take Trubisky because Mayfield is more of a turnover machine. One thing they have in common is that they both can make their WR's look ordinary. Mitch is a single read QB who cant spread the ball and he doesn't throw receivers open, so if you're not Allen Robinson you'll never have a big game. And Odell Beckham Jr. has been held to career low numbers playing next to Mayfield. I would hate to be a WR playing with either two of these guys, because as a fan if I had one game to win I'd take Trubisky because he'd throw less INT's whereas Mayfield is a dude who regularly has 2 or more picks in a game. In a 16 game season, Mayfield has the potential for 20 interceptions.
