I don't think that is fair to classify Unitas and Marino as game managers. Griese sure. But Unitas had an excellent arm, made plays deep downfield and was a big reason why the Colts won late in games during his career. Marino was a talented thrower and could make plays in the pocket but he relied too much on his arm to win games, no thanks to Shula. Marino was also an arrogant dick that was always quick to blame everyone but himself for why his team lost.
No, no I meant that Unitas & Marino were game breaking QBs, not game managers like Griese was. Both Unitas & Marino could change or win games with just one throw. Griese was never a threat to do that.
I agree with you about Marino being an arrogant dick btw. His teammates must have loved him after he threw them under the bus
