I'll go with SF's choices while noting Calvin was shut down when they played the Dawgs.
Calvin Johnson is a weird case... He probably shouldn't have been at Georgia Tech. He was a man among boys out there on the field, and shouldn't have been on an option team for who throwing the ball was merely done to keep a defense honest.
His final season (his most productive) he only caught 76 receptions. To be in the top 100 single-season receptions leaders you'd need to be >=102. There aren't good stats in CFB on targets, but my guess is that it's not like he had poor reception numbers on high targets; I'd assume he had stellar reception numbers on low targets. Because he was unstoppable when the ball came his way--it just didn't come his way very often.
So... To your point. For Georgia Tech, throwing the ball was a "constraint play", the thing you do when teams are selling out to stop the option and you want to force the defense to keep you honest--so you can be successful running option. Well, when you're playing a big-boy football team, they can stop the option in base while still covering receivers... So "constraint plays" don't work.
So I'm not sure UGA "shut down" Calvin. I think they shut down the option, which shut down the entire offense, and thus there was no way for Calvin to have a role. They weren't a passing team. Looking at the 2006 game (Calvin's final season), GT only gained 188
total yards against UGA. For an option-first, run-first team, with Reggie Freakin' Ball as their QB, they weren't built to force feed him in the passing game. It just wasn't their game.
All that said, it possibly limits the degree to which we should consider him a Mt Rushmore candidate. I feel like you want a Mt Rushmore candidate to be the focal point of their offense. And Calvin Johnson wasn't that. He was INSANELY good. But he wasn't the focal point.
