Poole has an outside chance at being a lead guard. The problem with looking for a "Klay Thompson type" is that every team in the NBA is looking for them too.
Wesson shot 42% from 3 last year and hit 80% of his 3s in the pre-draft trials, by far the best among all bigs. So while he doesn't bring in elite athleticism or wing defense he DOES bring shooting and rebounding and something completely missing on the Warriors at present in post scoring.
