At Central Florida, Bruce Miller was an all-conference defensive end. Then the 49ers drafted him and moved him to fullback. With the arrival this year of coach Chip Kelly, the 49ers no longer use a fullback, so Miller’s position changed again, to tight end. But in recent practices, Miller has been trying a new position again, lining up at wide receiver.

“He’s playing both tight end and move tight end for us,” Kelly said on 95.7, via the Sacramento Bee. “And he’s playing a little bit of wide receiver for us. And he’s really adapted well to it.”

Miller said he has lost some weight, and 49ers offensive coordinator Curtis Modkins said that’s helping Miller with his speed.

“He can run,” Modkins said of Miller. “He’s an aggressive personality because he has some of the other side of the ball in him. He understands football because I think he’s been exposed to a lot. He can just do a little bit of everything pretty good. So we’re excited about him.”

If Miller can’t change positions effectively, there won’t be a position in a Chip Kelly offense for him. Fortunately, when it comes to changing positions, Miller has experience.
