The San Francisco 49ers hope to have an offense dedicated to making big plays downfield in 2015.

"Vernon is stretching the field," Jim Tomsula said Tuesday said of tight end Vernon Davis. "Vernon looks extremely fast. Catching the ball really well. Again, the next three days, I’d rather you watch it then me talk a lot about it because you’ll have the opportunity to see it.”

Torrey Smith, the team's most prominent free-agent acquisition, caught 213 passes, scored 30 touchdowns and averaged 16.9 yards a reception in four years with Baltimore. Last year that average dropped to 15.7 yards a catch, but he also scored 11 touchdowns.

The 49ers believe the downfield threat will also create more room for their running backs, as well as Anquan Boldin for the intermediate throws.

Colin Kaepernick believes he's now more accurate than he's ever been.

"It's something that we've (the 49ers) worked on more, too," he said. "We added the weapons to go down down the field. That's something we've got more reps at, we've gotten more comfortable with. Hopefully, that carries over."
