"But it didn't enhance match fitness for the core, and it effectively created a situation in which Mann scored the game-winner when Wando had a handful of key players off the pitch."

I don't know if you meant it this way, but this sounds like you are placing a lot of blame on the subs. The "key players" didn't have enough time to get the job done? And they couldn't get it done because they weren't fit enough? The Wando bench isn't deep enough to sustain a handful of substitutions?

Perhaps there should have been more subs if match fitness was an issue? More like what Wando reportedly did the rest of the season? With a bench supposedly that big and deep, that's apparently gotten so much playing time all season that "All the mommies and daddies were happy that Nos. 24-32 were getting significant varsity minutes" - why change if it ain't broke?
