Wilhoite worked his way up from the 49ers practice squad, eventually earning a starting role. He took over as starting inside linebacker in 2014 when NaVorro Bowman tore up his knee. Wilhoite remained in the starting lineup in 2015 after Patrick Willis retired. In 2016, the 49ers ended up in an extensive rotation at inside linebacker. He appeared in all 16 games, but was listed as a starter in only six.
Wilhoite will likely be primarily a special teams player who provides some depth in case of injury. You could say he’s kind of replacing new 49ers linebacker Brock Coyle. During his time in Seattle, Coyle got some starts when players got hurt, but was primarily a special teams players. It would seem he and Wilhoite are effectively switching roster spots.
