If you're going for a KR/PR role, I would argue Juke is broken and Head Fake is the only thing that works. Though I'm basing that data off CB's, my theory is Juke is broken for nearly all returns:
http://goallineblitz.com/game/forum_thread.pl?thread_id=3749672&page=1If based purely on receiving, here's my take on it... the "catch %" chance is arguably better than the fake %, so it's hard to recommend high juke or head fake for WR's when you're not taking advantage of its benefits via a % piece, and knowing Juke is a 5th tier SA, it's hard to recommend it. I'd go Head Fake, but don't go crazy with it. If you do go high Head Fake, consider a Fake % piece, but also consider you're depriving yourself of what could be a potential Catch % slot.
