Shaedon Sharpe shot just 31% from beyond the arc last season with the Portland Trail Blazers. It's an incredibly small sample size of just one game, but it already appears that he's drastically improved his shot this offseason.
In the Blazers' preseason loss to the Golden State Warriors, Sharpe finished with a game-high 22 points, shooting 9-of-15 from the field and 4-of-8 from beyond the arc.
He shot 36% from deep as a rookie, which is around league average. If this game was any indication, that is a reasonable percentage to expect from Sharpe this season. It's not just the one game, either.
