Watch: Calvin Johnson regrets 'Megatron' nickname in Transformers ad

Calvin Johnson had what might be the best nickname in pro sports history, "Megatron," but the former Detroit Lions wideout is annoyed by the moniker in a new commercial for the movie "Transformers: The Last Knight."

"I've always loved my nickname, but I think this Optimus Prime dude has me confused for some other Megatron," Johnson quips.

Johnson reportedly was forced to pay the Lions back at least $1 million after retiring early, so it's nice to see him making some of that cash back with this commercial partnership.
