Spurs guard Manu Ginobili is a basketball player foremost, but he is a fan as well.

There are times he watches the historic brilliance of LeBron James and the Miami Heat, or the made-for-“SportsCenter” athletic dominance of Kevin Durant, Russell Westbrook and the Oklahoma City Thunder, and can’t believe the Spurs are in the same league with those teams.

“The talent they have, and the depth, the crazy shots they make,” Ginobili said. “Then we look at the standings and we are on top.”

Neither snow, nor rain nor loss of an All-Star point guard seems to be able to permanently slow the Spurs’ roll.

If there was a question about whether the Spurs would crater over the next month while catalyst Tony Parker nurses a sprained left ankle, they answered by winning their first two games without him, over Detroit and Chicago, by a combined 57 points.

At 48-14, the Spurs enter tonight’s game against Portland 2 1/2 games up on the 45-16 Thunder for first place in the Western Conference.

The Heat have needed the longest winning streak in franchise history (16 games) to pull within .011 percentage points of the Spurs atop the league-wide ledger.

“I think the character of the guys, the focus and the professionalism, is the reason we’ve been able to sustain everything,” Spurs coach Gregg Popovich said. “They’ve got a lot of pride in what they do, and I think they feel responsible to each other.”
