Wish I knew how to create a poll, but looking at the schedule, we'd need to go 9-7 (starting with the upcoming Laker game) to hit 50 wins by the end of March. I'm going to predict that we go 9-7 and on March 30th we have our 50th....and on April 1st we win #51 against the purple and piss. So March 30th is my answer.
Here are my guesses Mon, Mar 3 vs Los Angeles W (42-18) Wed, Mar 5 vs Atlanta W (42-18) Fri, Mar 7 @ Dallas W (43-18) Sun, Mar 9 @ Houston L (43-19) Tue, Mar 11 @ Memphis W (44-19) Wed, Mar 12 @ San Antonio L (44-20) Fri, Mar 14 @ New Orleans W (45-20) Sun, Mar 16 vs Golden State W (46-20) Tue, Mar 18 vs Milwaukee W (47-20) Thu, Mar 20 vs Washington W (48-20) Sat, Mar 22 @ Charlotte W (49-20) Mon, Mar 24 @ Miami L (49-21) Tue, Mar 25 @ Orlando W (50-21)
