The Suns need 3 point shooting. Ayo can't shoot. He sure as heck cannot run any point.
He can help a team in NBA, but really is kind of a fringe guy until he develops a 3ball.
Fringe is exactly what the Suns can afford first off, and as far as 3pt shooting goes....Durant was 31dt in %, regular season, Booker was 3rd in playoffs, and Craig was 18th, Payne was 24th and even Shamet (now gone was ranked).....I think they can do just fine with having those guys as well as having Booker lead the playoffs at 33.7 per and also58.5% FG overall in playoffs, and 50.8% 3's in the playoffs.
3 pt shooting is not what the Suns are missing....they need reliable players, proven who can contribute and not cost them max contracts to go with their big 3 of Booker/Beal/Durant. Ayo/Leonard would fit needs and be very functional without breaking the bank now. Leonard would also add some rim protection, some athletic ability and also some 3's as well.
