3-whistle coverage in transition

[Dan_ref]

Chuck, with your speed I know you were ahead of this play
and could treat this as normal coverage. But some folks
can't treat this as normal coverage because they're just
in front of the play or they've stopped at the FT line
to see what happens. In any case, I'm thinking unless
you've clearly beaten the break & are in position why would
the L not take this play? Did your observer say anything
about this or double whistles on the break?
