Is it though, when they have demonstrated an inability to succeed at the highest level?
If the definition of insanity is doing the same thing and expecting different results, it seems quite reasonable to attempt to rework a swing that has arguably failed.
Perhaps this is parsing language too finely, but I think "abandoning the swing" is overstating a bit. The swing itself looks pretty much the same to me, it's the stance and load that has been altered.
