If Sergio has indeed developed an outside shot, or even just the ability to make a layup, something he wasn't able to do in 4 seasons in the NBA, he may actually have a role in the league. While he was in the NBA, he was a poor man's version of Bricky Rubio, a flashy passer who turns the ball over way too much and can't score to save his life. At least with Rubio you get his high risk/high reward gambling defense. With Sergio, you get no defense at all.
I do like the beard though. He has kind of a euro-Harden thing going on there. One would also hope with another 4 years playing in Europe he would have vastly improved his flopping skills. Better flopping, combined with an outside shot, may actually earn Sergio a role as a decent back-up PG in today's NBA - something he failed at miserably his first time around. But, I doubt he'll come back. He's finally a star somewhere. I assume he makes good money and has a shorter, less grueling season. Plus, given that so many Spanish players have scruffy neck beards, I'm guessing that's a real pantie pealer with the groupies over there. Why would he ever leave?
