PLaybook question I wanted to ask you guys a gameplay question. In my playbook (I run a pro style), I have a number of ACE, I, Strong, and Weak sets. When I audible between them, I typically run a WR across the formation (from normal to twins or the reverse) shift a TE from one side to the other (Ace Big to Ace Twin TE, for example) or move the FB from the I to weak to strong. I assume these shifts are kosher, since they happen in the real game all the time. My question is about shifting the TE into the FB slot. Now, I've seen a lot of teams do this, (Pitt does it on nearly every play) and it's built into the game this year (there's a number of plays with built in motion that shifts the TE into the FB spot and sets that feature a FB in a TE spot, like Ace F Pair Twins). Anyway, I thought I'd ask because, in the past, throwing to the FB was an issue. I'm not trying to set up a pass to a TE in the flat; most of the time the TE becomes a lead blocker. I'll dump the occasional pass into the flat if I get a heavy rush, but everybody does that. Anyway, my shifts mimic the real game, but I know some folks don't like audibles. I love them because they give me the largest number of options out of any playbook. But I thought it would be a good topic of discussion. What shifts are cool, and what shifts are not? For me, WR shifts are fine, but not into the backfield. TE shifting back is fine, and splitting out is fine (but only one - no Big to Spread stuff). HB to slot receiver is fine, but FB to receiver is not. Anyway, I thought it would be a good question to ask.
