Never, ever quit. What, you thought that was just one of those trite sporting cliches? Brandon Roy shot that notion down Saturday at the Rose Garden, right along with the Dallas Mavericks' hopes of seizing the advantage in their first-round playoff series with the Trail Blazers. Roy reached deep into his bag of heroics when the Blazers needed it most, scoring 18 of his game-high 24 points in the fourth quarter of Portland's see-it-to-believe it 84-82 come-from-behind victory. Rather than head to Dallas for Monday's Game 5 trailing 3-1 and looking at elimination, the Blazers go in tied 2-2 with momentum in the series. "A great day for me and the team," Roy said. "We've got some pressure on (the Mavericks) now." Rose Garden denizens will be talking about this one for years. The Blazers were dead and buried, trailing by 23 points late in the third quarter, and members of the media were already writing their epitaph - in the game and the series, too. Then Roy - maligned and battle-scarred through the most trying of seasons - led a stirring rally that left him, he admitted, with a surreal feeling. "It still doesn't feel real yet," Roy said after sinking 8 of 10 shots in the fourth quarter, including the game-winner with 39.2 seconds left. "Just an unbelievable game, the comeback. "An incredible game to be a part of." With the ball in his hands nearly every possession down the stretch, Roy was scoring from everywhere - the 3-point line, the foul line, from mid-range.
