I would not be surprised to see Vezenkov come in for a spot in the second half. It's odd that Coach Brown is still experimenting with lineups this late in the season, but the weakness of the starters this year, compared to last, has forced his hand.
So far as Sasha goes, if there is a trade shipping off two players, time will open up for him in the last third of the season. He is seasoned with lots of European playoff experience.
