He's not.
Schultz blew a couple blocks and so got a bad reputation. He is a competent blocker, same as Fergie.
Their agility is close, but man, it was fun to watch Schultz's agility in YAC. Dude looked like he was playing twister out there. Most fans didn't notice because they were too busy hating on him, which was ridiculous.
And here's the biggie. Schultz was a master at creating separation. We have no idea if Fergie can consistently get open. I know, I know, we THINK he can, but that is far from the doing.
