Marino has a huge ego. His biggest nightmare is Luck becoming a south florida icon and everyone forgetting about marino.
Because every where else in North America Marino is laughed at as a loser who never won a super bowl. Only in south florida does Marino have a good reputation and he's scared that Andrew Luck will make Marino a forgotten man in south florida when Luck wins multiple super bowls as a Dolphin.
Screw Marino. He had 17 years of chances and he didn't deliver when it was needed most... He looked piss poor in too many playoff games to remember. His playoff numbers after his first 3 years were awful. Getting shut out in 2nd halves of very important playoff games. INT after INT after INT,, after stupid pass after stupid pass after stupid pass,, after stupid decision after stupid decision after stupid decision,. Look at Marino's playoff games over his final 15 years and it was mediocre performances at best,, for the most part (with many embarrassing playoff performances thrown in there).
He had his chances and failed time and time and time again. Time for Luck
