Spencer Hawes and Evan Turner had to laugh. Shortly after holding off the two-time defending NBA champions for a 114-110 opening night victory (see Instant Replay), the teammates thought back to their first season with the Sixers.

“I was joking with Evan. We were talking about when we first got here how we had a lot of games just like this one early in the season and we found a million different ways to lose them,” Hawes said. “We needed this.”

Some of those losses during the 2010-11 season were unique, like the one in which the Sixers lost to Washington on a late four-point play in overtime. There was another OT loss in Washington, too, as the Sixers opened the season 3-13.

The difference between those losses and the victory on Wednesday night at the Wells Fargo Center was hardly a subtle one, according to Hawes and fellow veteran Thad Young. First, the Sixers opened the game with a 19-0 run, built up a lead to 22 points and rallied in the fourth quarter after allowing 80 points in the second and third frames.

The Heat played the second game of a back-to-back without Dwyane Wade. However, with 80 points in the second and third quarters, including 10-for-13 shooting on threes in the third quarter, it looked like the Heat would survive without the perennial All-Star.

That was until the Sixers’ rookie point guard, Michael Carter-Williams, took over.

Down by eight points with 4:30 to go in the game, the Sixers stood up to LeBron James (25 points, 13 assists) and the Heat with a remarkable amount of poise. Call it steely nerve and veteran know-how all over the floor from Hawes, Turner and Young.

But more than that, unflappable point guard Carter-Williams played as if he had been in the league for 10 years. In the final three minutes of the game, Carter-Williams grabbed three rebounds, handed out three assists, grabbed a steal and stepped up to the foul line to make five out of six foul shots, including a pair with 8.5 seconds left to seal the game.

Believe it or not, Carter-Williams showed that poise and grittiness in his NBA debut. With 22 points, 12 assists, nine steals and seven assists, Carter-Williams did just about everything and then some. The double-double is the first by a Sixer since Maurice Cheeks did it in his first game in 1978. The 22 points is the most by a player making his debut since Allen Iverson scored 30 in 1996.
