The only full game I've watched of Mariota was the first game. I just had to go back and watch that game, as it looked at the time like we were witnessing a star being born. He reminded me of a more athletic Brady in that game. I was in awe. Then he came back down to earth, and I quit following him so closely, and have only caught a few possessions here and there. From the few snaps I've seen outside of the first game, he started to remind me of RG3 a little bit, and not in a good way. It seems like he just doesn't know how to protect himself, doesn't know when to quit, risking his body/health/the team's future in the process, and on top of that seemed real loose with the ball when under pressure, i. e. waving the ball around perilously in one hand looking to throw it even while being dragged down by pass rushers. While watching, I'm talking to the TV screen, "Just eat the ball! Live to play another down. Also, don't risk giving it away like that." Maybe that was just rookie growing pains, maybe he's improved on that, but I don't know, as I haven't watched him enough.
