C.J. Watson spent the past two seasons playing behind Derrick Rose in Chicago. But even after seeing the NBA's 2011 MVP up close on a daily basis for the past two seasons, Watson said he thinks his new teammate, Deron Williams, is the league's premier point guard. "I always thought Deron was the best point guard in the league," Watson said yesterday during his introductory press conference at the Nets' practice facility. "When everyone asks me who is the toughest point guard, I always say him. "Between him and D-Rose, it's pick your poison."
