I don't like Fuller's chances in the NFL at all. First of all, despite his size he has problems getting off the line. He's also had alot of problems against press coverage and that's quite sad given his size. He also lacks explosion and lacks good speed. To top it off he also stands too much before his breaks/cuts and is not a swift cutter in some of his routes, though he does flash good feet on cuts in certain routes.
He also has very long legs and is a very long strider in the Ted Ginn mold , so when you combine his long stride with his lack of explosion and lack of speed it's not good news-- so with being a long strider you really can't use Fuller in the slot , only on the outside and I just don't see him being able to evade NFL starting corners with his skill set, or lack thereof.
He's also not good after the catch and takes time to change direction. Although he is poor after the catch and has poor field vision his agility isn't too too bad, and he has a nice catch radius and can catch a ball if its anywhere around him (in this regard he is far better than Hartline for example who sucks at this as he's not a good fighter for the ball in traffic and loses those battles far too often given his size)
People point to Fuller's season two seasons ago but he was also quite poor in his final 5 games. He had under 40 yards receiving in 4 of his last 5 games. He had big yards very early in that 2010 season against poor opposition.
I like Rishard Matthews as a prospect 1000000X more than I like Fuller. And so should you. Fuller was just brought in here to help out Tannehill a little in some early camp bumps on the road. If Miami didn't draft Tannehill, Jeff Fuller wouldn't be here and you can be certain of that.
