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 Mavericks season is mercifully over after losing in five games to the Houston Rockets. While Dallas put up a good fight despite the absence of Chandler Parsons, its fate was all but sealed after a Game 2 loss in Houston that ended with Rajon Rondo on the bench for the final 23 minutes.
