Rudolph was out for a portion of the season with an injury, but his performances when healthy left at lot to be desired. He caught 30 balls for 313 yards and three scores in eight games played as the number six tight end in average draft position. He struggled as his offense kept shuffling quarterbacks. This year should be better, but I'd keep a watchful eye on his preseason performances.
I love Rudolph's talent, but until the Vikings find him a quarterback that can throw the ball consistently, he is going to struggle to put up big fantasy numbers. Playing in Norv Turner's offense could be a big boost for his fantasy value.
