When it comes to physical attributes, no other tight end is more naturally gifted than 49ers tight end Vernon Davis.
Back at the NFL Combine in 2006, Davis ran a sub-4.4 forty, posted a 42-inch vertical jump and bench pressed 225 pounds 33 times as a prospect out of the University of Maryland.
In his first three NFL seasons, his production was much less than his potential would otherwise suggest.
Davis had a breakout season in 2009 with 78 receptions for 965 yards and 13 touchdowns, but since then his yardage and touchdown totals have declined each season.
