Expand on this, please.
The more I read my last post, the more pessimistic I feel. JT showed very obvious development, as seen by where he stood in league scoring those first 3 years. Jack appears to be fairly stagnant relative to his competition. We assume he's got so much more than he is showing. Could we be that wrong?
Plenty of players take a "step back" during development. More often that not, actually, they'll have a point in development when they slump.
Jack hasn't been stagnant at all. He took a huge step forward last year after a really good rookie year. He's taken a step back this year (through only 30 odd games), but seems to be coming on lately.
I don't see a reason to be pessimistic yet.
To be honest, unless JBot can assemble and uncommonly good supporting cast, that is my expectation.
You don't need an uncommonly good roster to not be mediocre. You just need a good one.
