Smart move by Obekpa to return for net season.
Look for substantial improvement in the quality of play of Christian Jones.
Don't hold your breath on the second point.
There is a lot of evidence for you to hold that belief, but:
A long time ago, a brand new college coach took over a mediocre squad. In meeting one of his upper class players, he essentially told him, you're fat and out of shape. If you want to play, you'd better start working hard, starting now. The kid worked his tail off, dropped 20+ pounds, and was given the reigns to the team.
The kid led the team to the Final Four. His coach: Rick Pitino. The kid: Billy Donovan.
Sure, those stories are few and far between. But I could tell you one about a so-so guard given a shot to be "the man" on a team that had never done more than play one NIT game the previous 6 seasons. That kid lit up the Garden, including destroying eventual national champ UCONN by outplaying Kemba Walker, and electrifying NY with a last second basket vs. Pitt. Hint: Mickey Rooney made a ton of money in a series of movies with the same last name as the kid in question.
Don't write anyone off in a new regime. Sometimes the deck gets shuffled and guys emerge.
