Jeremy Maxa Member February 27, 2021 at 4:40 am This came up in our off-season discussions about 5 years ago. After looking through years of IZ plays, we found the plays with 2 interior double-teams were the ones that got positive yards — not always huge gains – but not negative plays. We found the biggest killer to IZ was penetration by the interior DL. When this happens, RB’s are limited to their options. With two double teams inside, this was significantly cut down. So to get these double teams, we had our Qb check to the 1 tech. on EVERY SINGLE IZ. This was a 100% check. Now, you still need to practice running it to the 3 tech. as well (especially vs. teams that stem or bump their front during the cadence). But the biggest reason running it to the 1 tech. was the reduction of interior penetration.
