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.
This success created an aura around the Boston Celtics in the NBA Playoffs that is unlike any other team in the NBA. The Boston Celtics Playoff fortunes stayed bright throughout the next three decades, with the team adding NBA Finals victories in 1974, 1976, 1981,1984, and 1986.
