Honestly those wins we didn't look that great. We were pretty.. basic. I dunno we just never looked great this season. Every game was like THAT Saracens game in the build up to the Prem final in 2020. We weren't that great, but got the job done. Same was those games.
That aside, it took a lot of energy to play consistently against big teams, and it knackers you.
I don't think we went good, then bad. Just had fortunate results briefly.
Stand by it, our attack has been stiff and lacking this season.
I'll add another suggestion no one here's mentioned, I've heard Mitchell has a history over training players. Might not be related to form, but potentially injuries. Sometimes coaches other than Eddie Jones can be blamed.
