Hi Wayne, Go ahead and use PEX, I have always used the Wirsbo Brand...there are as many brands as there are Chinese manufactures of everything else plus there are quality brands, and everything in between just as everything in life...you get what you pay for.
No team has ever come back from a 3-0 deficit in a playoff series. The 1951 New York Knickerbockers, the 1994 Denver Nuggets, and the 2003 Portland Trailblazers came back from a 3-0 deficit to tie the series at 3-3, but neither won their respective Game 7. Eight teams, however, have rallied back from a 3-1 deficit.
The Lakers ran out of gas in the 1959 NBA Finals, however. They faced the Celtics, who owned an 18-game winning streak against Minneapolis and had demolished the Lakers, 173-139, in the teams' last meeting. When the dust settled, the Celtics' winning streak was still intact-Boston swept the series in four straight.
