Mike,
could they be herding bait and these are the outer ring sentries
while a sheet load of schoolies(out of frame) are forcing them closer to the shore and mawing-down as the front line of attack? these bigger fish could be looking to corral/prey upon any bait that tries to make a run for it.
one of my first blitzes 5yrs ago was not unlike this, on a much smaller scale, off of Deer Island. little guys tight to the shore beaching bait, and engulfing wild eye storm shads ~~~while the bigger swirls were just out of reach of me white Wally World Shakespeare noob stick
