Yeah, they called it a 3-3-5 there, but it’s really a 5-1 and they aligned it as Bear to move the box that the offense would have open in run game (which is why your DE’s squeeze the B). I figure you’ll have your LB’s spill any pullers, but not sure of that.
When coaches call it all this different stuff, they do so to make themselves sound exotic. Ha
But calling it a 5-1 nickel is more intuitive to average fans (not meant as a pejorative). You hear that you immediately think 5 on the line, 1 LB, then nickel is 5 DB’s.
