Line splits between OL to include a TE if you choose to have one or two are a standard Rookie base-width apart. Looking at the picture below, you see that the OL spaces (white) are separated by black spaces. That is the line split, and if you remember from your days of playing real football, those are actually the holes. This is more than enough room, initially, for the OL/DL to have their individual battles and allows for LBs to fill holes instead of pushing a DL from behind!?!?!?!?!?! At the same time, it allows the FB to get in there and block that filling LB, which leaves the RB to make his cut based on his FB's block and the only guy to beat is the SS, like it should be.
