Former wide receiver Keyshawn Johnson is considering a move from the studio back onto the playing field, according to ESPN.com. Johnson has been working out regularly and is contemplating resuming his playing career. "I like challenges," Johnson told Yahoo! Sports earlier this week. "The challenge of helping to turn a team around, to help get it to the next level, that gets my competitive fires burning. I have the itch, and right now I'm trying to decide how strong that itch is."
