The players lost their consistency as a team. It became a 'bring yer boots' team, where nobody really knew the player next to them. That is telling. Wasps, as a 'brand' should have a plug 'n play training regime, where the style and plays of the team are known by all who play in any position. But, they are clearly not anywhere near close to that. The backs more so than the forwards. A 12 should pretty much know what his 10 will do when a plan goes awry, but they don't. And so on. It's like they don't sit down and discuss things before and after training sessions.
Sure, Jacob might Booj, here's what we are going to try now. But, no discussion of what Jacob will do if the ball comes too slow to him, or too high, or behind him. No backup plan. It goes from planned to panic.
