The big reaction from Phoenix Suns fans when it leaked that they'd signed Sonny Weems was "who?"
Then, when Paul Coro reported that Weems might be the first guard off the bench next season, the reaction was "Why?"
Take a look at this scouting report by the incredible Mike Schmitz. He put this together in 2013, when Weems had first broken out in Europe after leaving the NBA. Weems decided to stay in Europe as the highest paid player in the league, and kept up his consistency for the next two years.
He hits 36% of his threes over the last three years. 37% last year. But his best attributes are playing within himself, making the right plays, giving up the rock for the better shot, and defending on the perimeter.
Now he's back in the States. Check out his strengths and weaknesses here. Looks to me like he's a perfect fit for what the Suns need.
