Yeah I mean I think the holmes route he could stop at the end of it or be instructed to keep the routes alive and roll with it because honestly Josh Allen is an improvisational kinda guy so to me I agree with the twitter OP who said the receivers keeping them "Alive" (continuing to run, try to get open and create a play) seems to me like what all of our guys should be doing every play.
On the benjamin route, I agree I feel like he was supposed to be crossing over mid field by that point and he was not but at the same time who knows I'm not exactly sure what he has been instructed to do on that play and I'm sure Cover1 isn't either.
