While setting a physical tone for the 49ers, Boldin racked up 208 yards and one touchdown on 13 receptions to give him the second- and sixth-highest totals for receiving yards in an NFL season opener. Boldin recorded 217 receiving yards in the Arizona Cardinals' 2003 opener against the Detroit Lions.
Boldin's highest total in three years with Joe Flacco was 145 yards, which suggests Kaepernick is a star maker for No. 1 receivers after doing the same for Michael Crabtree last season.
After watching the Packers spend the offseason studying the read option, innovative 49ers offensive coordinator Greg Roman eschewed the zone read and beat Green Bay's defense through the air. Kaepernick's 412 passing yards are the most by a 49ers quarterback on opening day, besting Steve Young (363) and Joe Montana (356).
