That's not a surprising development considering how well Boldin fit in last season in his first year.
The 49ers made the playoffs and Boldin caught 85 passes for 1,179 yards and seven touchdowns.
He was acquired via a trade from the Baltimore Ravens for a sixth-round draft pick.
Boldin, 33, remains a physical player who routinely makes contested catches.
The Ravens were unable to replace him adequately and missed the playoffs, finishing with an 8-8 record.
