Jake managed to make this block at an important point in the game when the Los Angeles Lakers team was winning the game, but it was the Portland Trail Blazers team that was playing best in that third quarter.
So if the Los Angeles Lakers team prevented this attack from the Portland Trail Blazers team, they could still maintain the advantage in points, but in this game, the Los Angeles Lakers team was not able to gain as many rebounds as they normally did in games.
So Wallace still managed to catch the rebound and make the 2 points even after Jake made the block, this again gave hope to the fans and players of the Portland Trail Blazers team and did not give the cheer to the Los Angeles Lakers team that Jake expected.
The third quarter ended with the Portland Trail Blazers winning by a few points, the Los Angeles Lakers team could get the comeback in that quarter, but it looked like the Lakers players were out of luck.
