I agree. I understand the caution about late-season signs of life (in previous years it's been when support grows to keep the interim manager for next year), but these were structural improvements in the team. Also, we aren't remembering just how devastating the injuries were for most of the season. Off the charts, legendary amount of injuries.
I guess the one caution now is whether the off-season moves will create another set of poor lineup choices that the team eventually has to overcome to right itself.
