It looked like Limmer just missed the assignment. Unless Stafford called the protection differently.
The Right guard helping the Right tackle on that play is how it’s supposed to go.
It's not that simple. It's the NFL; and you are giving Dotson too much of a pass here.
Only one rusher was to Carter's left, rushing the Rams right side; and he did not come inside at all.
Havenstein was in good position, and it was a quick pass play.
Dotson could have, and SHOULD have, looked both ways. All he (or Limmer) needed to do was get in front of Carter. That well could have beeen enough time. Dotson has to have his head on a swivel.
Consider who Carter is. An elite DL ... the Eagles' best defender ... and Limmer AND Dotson let him run free.
Aaron Donald did a Chris Long podcast; and was asked who he hated playing against the most and why.
Donald answered the Eagles because on every snap, Jason Kelce went to double-team him.
Donald would yell at Kelce that he had good guards ... why not let them block him one-on-one some times.
Kelce responded ... 'We are not going to let YOU take-over the game'.
Imagine at a critical moment, a Rams' opponent not even trying to block Donald, allowing him a free run.
It's absurd. Yet, that's exactly what the Rams did with Carter. Neither Limmer, NOR Dotson deserve a pass.
