To be fair, Hilliard was an RB that they moved to FB and he supposedly could catch. He had a few blatant drops, but fits the kind of mold as Baker. I like Baker, but I think his injury was very severe and he was a borderline prospect to begin with. I'm not into burning a draft pick on a FB, but a guy in the 5th or later that is a serious special teamer isn't a problem in my book. Much prefer a FB that can catch. Conner didn't seem to excel in that department, but Sanchez never looked good throwing to any backs.
To play a FB that rarely catches the ball is to signal to the opposing defense when you're running. Like when Schotty would line up Conner out wide, and then....oh wait! he's motioning in to block!! Nobody was surprised. Might as well get a defensive lineman like Pouha to come blast a hole on 4th and 1 to serve that purpose...and not take up an entire roster spot.
Now, if we could find a bigger bodied back who could serve multiple purposes like:
Anthony Dixon, who can pass block, lead block, or run the ball on his own merit (short yardage).
Marcell Reece, who is a dual threat, and actually started at RB when his team got banged up.
James Casey, who is listed on paper as TE/FB/HB (at least in my fantasy league).
No more pure FBs unless they are Mike Alstott good.
