Once again, the advice from forks and aircraft is fine in general, but not in Ohio. Both coverages and relaying the ball are covered in the "gold book," and the expectation is that you'll do it that way.
FYI, BJ takes the inside receiver on the LJ side in twins and the two inside receivers in trips. Switch to zone coverage on long pass plays. BJ relays the ball on gains of 10+ yards, otherwise R does it.
Of course, if you happen to be on one of those "screw the gold book" crews, then I suppose it will look better to work consistently with your crew.
