Behind Stevie Johnson's well-known buoyant, impish personality is a competitor.
The Buffalo Bills' star wide receiver hates to fail, in any way, and he doesn't want the world to know he's so fiery about it.
In fact, only one teammate knows sometimes when he's seething.
"He's definitely a 'personality' to you guys in the outside world," fellow wide receiver Donald Jones said in an interview Friday before a stop at a downtown Toronto apparel store to promote Sunday's Bills-in-Toronto game against the Seattle Seahawks.
