Excellent points people!
It makes MUCH more sense to have Williams in the slot. The depth chart right now means nothing and is usually based on nothing more than seniority. If that was the case, then VD would be ahead of some of these guys at WR given he's been practicing there as well. This is how is should shape up.
X = A.J. Jenkins/Ricardo Lockette
Y (slot) = Quinton Patton/Kyle Williams
Z = Anquan Boldin
PUP = Mario Manningham & Michael Crabtree
It's an excellent point about AJ once the pads go on. Can he out-muscle a Dick Sherman at the LOS? Most likely, he won't be able to but he can mimick Manningham's game and create excellent separation by quickness and explosion off the LOS...it's all technique and hand-fighting, cutting, diguising your routes, studying the CB's you'll be facing, knowig our game plan, when you will be featured/called on, etc.
