49ers signed Utah WR Dres Anderson.
Anderson (6'1/187) graduated fifth all-time in receiving yardage for the Utes, parlaying 134 catches into 2,077 yards (15.5 YPR) and 17 TDs. He is the son of ex-Rams WR Flipper Anderson. Dres tore his left meniscus last October and required year-ending surgery, preventing Anderson from testing at the Combine. He did clock 4.43 at the Utah Pro Day. The reddest flag on Anderson is an 18.6-percent drop rate between his final two college seasons. He is a leggy, straight-line burner who may have to make his NFL living as a low-volume vertical streaker.
