Add Vernon Davis to the list of those not thrilled with offensive coordinator Greg Roman this season. That’s certainly the impression the Pro Bowl tight end gave off today when asked about his 25-catch, 236-yard, two-touchdown season. “For me, it’s all about coming here, showing up and doing what I have to do to contribute,” Davis said. “As far as not getting the ball, (I) leave it up to the offensive coordinator. It’s his call.” This season, Davis, 30. is averaging 4.1 targets a game. Last year, he averaged 5.5 targets a game and had 52 catches, 850 yards and 13 touchdowns. Davis has dropped 6 of 31 catchable passes this season and his 19.4 percent drop rate is the second-highest among NFL tight ends, according to Pro Football Focus. In addition, his blocking, which has been a strength, has declined. According to PFF’s grading system, his run-blocking grade ranks 56th of 65 tight ends.
