The Facts: Robinson’s struggles last year showed how difficult it can be to switch positions while trying to make the transition from college to the NFL. Robinson never got enough reps at one position to get in a groove. He played just 52 snaps all year and lost fumbles three times in games. Now, Robinson’s role is more clearly defined. He plays one position. “He understands he is a running back,’’ said HC Gus Bradley.

Diehards Line: Robinson, who as a sophomore at Michigan became the only player in NCAA history to pass and run for more than 1,500 yards in a season, didn’t have a position in the NFL. He ran the ball, played some wide receiver, some Wildcat at quarterback, some kick returns and special teams work. According to Times-Union staffer Vito Stellino, Robinson has embraced his new position and bulked up from about 197 to 212 pounds when he returned this week for the start of offseason conditioning drills. The Jaguars won’t be able to look at him in practice until organized team activities start next month, but Bradley likes what he’s seen of Robinson so far. “He’s a more confident athlete and I think he is really looking forward to this,’’ Bradley said. That said, Toby Gerhart was signed to be the lead back so Robinson will likely compete with Jordan Todman, who had 76 carries for 256 yards last year, for the backup job.
