SANTA CLARA, Calif. — Runnin’ Russell Wilson and the Broncos’ No. 1 offense got off to a much better start in their second preseason game. The Broncos starting quarterback engineered just one drive — a 13-play, 49-yard march that ended in a field goal after getting beset by a pair of penalties — before backup Jarrett Stidham got some run with the top unit Saturday night against San Francisco. Though head coach Sean Payton will certainly not like wide receiver Courtland Sutton holding on the edge as Wilson scooted for a big gain on a zone-read keeper, or Garett Bolles jumping early late in the play clock, the Broncos’ top offense looked sharper than it did on its opening pair of drives last weekend against Arizona. The two most interesting developments: Wilson’s work with his feet and a relatively heavy workload for Javonte Williams in his return from October knee surgery. Payton wasted no time getting Williams involved after saying during the week he wanted him to get a couple of carries and maybe a target in the passing game. In fact, Wilson targeted Williams on three of the game’s first four snaps — a drop on a screen and a 12-yard catch on the perimeter out of an empty formation and a 4-yard catch — and handed it to him on the other. Williams was heavily involved in the Broncos’ first two series and finished his night with three carries for 12 yards and four catches for 18. Wilson, meanwhile, used his legs to terrific results.
