Boston Celtics point guard Terry Rozier isn't done making a statement, after dropping a team-high 29 points in Game 1 against the Philadelphia 76ers, claiming there's more business to take care of during Thursday's Game 2.

“We can play a lot better,” Rozier said, according to Scott Souza of The MetroWest Daily News. “We had a lot of points that we gave up. We could have played even better offense. That’s the scary thing.”

The brash point guard added that there is an extra factors in this series, hoping to do more than just re-ignite this decades-long rivalry between Celtics and Sixers.

“We’ve still got more business to take care of,” said Rozier. “A lot of people are still counting us out. That don’t really matter. We’ve still got doubters to prove wrong. But we still have a lot of area to grow.”

The Celtics have already over-achieved, not only getting through the regular season through a horrific injury to Gordon Hayward in the opening minutes of the season-opener, but soldering on throughout the end of the season without two of their key cogs in All-Star point guard Kyrie Irving and spark plug Marcus Smart.

Having gotten past the Milwaukee Bucks in a stellar Game 7, the Celtics have shown they still have plenty left in the tank, showing it with a decisive 117-101 win over the Sixers on Monday.

Rozier, who started the season as a third-string point guard, has flourished, recently connecting in 7-of-9 from deep to help the Celtics in a 17-of-35 performance from distance en route to a 1-0 series lead.
