Calvin Watkins: Monday will have two of the better left-handed players in the game in Houston’s James Harden against Boston’s Isaiah Thomas facing off. “Lefties are just weird,” Harden said. “We’re just weirdos. The majority of players are right-handed, just catching defenders off guard, they’re not used to guarding left handers especially left handers who are very crafty. (Thomas) is crafty. He gets to the paint and uses his body and he’s always in attack mode.” What makes lefties weird? “I can’t tell you about that,” Harden said with a smile. “Next question.”
