I'll take a 25 y/o guy who shot 37.9% on 5.9 3s per game last year. This guy also averaged 17.8 ppg, increasing his average for the 6th straight year.
If he played for a better team with better creation, it is highly likely he would improve on his already good 57.7% TS%. He hit 50.9% on corner 3s last year, & would be an excellent person to free in the corner after some fun screen actions.
At 6'7, he can competently defend the 2 or 3. Defense is not the hallmark of his game, buuuut, he's not a complete stiff & would likely improve in an improved situation.
