Despite some up and down moments so far in his rookie season, Marvin Harrison Jr.'s drive to fulfill his sky-high potential has never wavered.
The Arizona Cardinals rookie told ESPN's Josh Weinfuss that he wants "to be great so bad" that it constantly pushes him forward.
"I just want to be successful," Harrison said. "I want to be great so bad. I want to help my team so bad, and I'm just always going to put my best foot forward for the team, and I think that's really just where it comes from: just go out there, have fun.
