Steve Smith led the league in 3pt % as a Spur. The comparison holds true because Finley doesn't do but shoot and he hasn't done that all that great all year.
Here's the thing though, all he was brought here to do was shoot and score off the bench. But because Pop uses him as a 4 when they run small ball, we need him to do more which is something he's never had to do before.
Finley will be fine if we count on him for scoring off the bench, but if we need him to do more then we might as well expect Beno to start dunking over people.
