Vince Carter drove the baseline and leaped, his feet hovering over the end line, when he reached out with his right hand and made a reverse layup. That was part of Carter's 14 points in the fourth quarter for the Dallas Mavericks, after O.J. Mayo's go-ahead spurt to end the third, and it almost wasn't enough against the New York Knicks. Dallas held on for a 114-111 victory Wednesday night after Carmelo Anthony was short on a potential go-ahead jumper with 4 seconds left, then fouled out when going after the rebound.
