Klay Thompson must have warmed up pregame in the Hot Tub Time Machine, because the vintage Thompson from a decade ago showed up in the first quarter Monday night in Dallas. Thompson knocked down seven 3-pointers in the first quarter on the Wizards.

"It reminds you that there’s greatness still within you," Thompson said after a blistering first quarter against the Wizards.

The Dallas Mavericks hosted the Washington Wizards on Monday night and got out to a dominating start, thanks to future Hall of Famer Klay Thompson. He scored 21 points in the first quarter, outscoring the Wizards by himself, as Washington had just 16 points in the first 12 minutes.
