He did have a surprisingly sucky championships, I'll grant that. Still, he had a very good season for Barcelona. He really needs to work on his jump shot. Also last year, in Eurobasket, he looked a lot better, so I don't know if they're using him wrong or he's injured or he's gotten worse.
I'd still rather have him than Teodosic (who made the all-tournament team at PG and who is a FA) who can certainly shoot but is too slow.
And, sucky as Rubio's stats look,
check this out -- which also should remind us, if we're bashing players on the basis of their performance in this tournament, it looks pretty crappy for Batum and Claver.
