It’s definitely his worst plan since that point, which is still quite fresh on everyone’s minds, and even though the good guys won this first big battle, it’s mostly because the Hilltop and Kingdom’s finest showed up and helped fight, not because Rick performed some brilliant act.
He did bring all the communities together, but people are going to start talking about replacing him again, and it’ll be harder to fight that logic after all this.
Jadis shot Rick inside of Alexandria, after he’d already hurt his hand in the Winston fight, so had something gone even worse for Team Family during the Saviors’ attack, Rick’s decision to trust them might have been an even worse move than attacking all the outposts and drawing Negan out of his RV.
