I do think 80 attempts (Ulis) is a large enough sample size to get a pretty good gauge of a what a player will consistently bring to the table. Kyle Wiltjer, who gets labeled as a 3pt specialist, shot almost the exact same percentage (43ish) on almost the exact same attempts (81) in 2012. The next year, Kyle's percentage dropped down into the mid 30's when his volume increased, but this by no means is the rule or the exception.
Historically other players such as Jodie Meeks, Gerald Fitch, and Tony Delk's percentages all increased as their volume increased. Lots of variables with all of that (player development, different year's team, experience, player's role, etc) but the reality is....
There's no way to determine for sure what will happen when his attempts increase (which I'm assuming they will) or what would've happened if he had shot the ball more this past year but to make the argument like you did that Tyler Ulis will not be a reliable 3pt shooter on next year's team is really a stretch.
So, next year we could have the worst shooting team in our history? That is disappointing, I wished Booker would have stayed. Mulder may be our only reliable shooter next year, although he still has to commit himself. - joester5612
