I cannot find his birthday, but him dying on March 21, or 21/3, at age 77, is likely a riddle with The NBA Finals.
3/21/2017 = 3+21+20+17 = 61 (Finals = 61)
3/21/2017 = 3+21+(2+0+1+7) = 34 (Murder)
3/21/2017 = 3+2+1+2+0+1+7 = 16
3/21/17 = 3+21+17 = 41 (13th prime)
He won his championships with Michael Jordan, who went to North Carolina, the Tar Heels. This could also be a clue for the men's tournament.
Notice how '77' connects to Chicago Bulls. The last team Jordan played for were the Washington Wizard, on the 77th Meridian.
Remember the Chicago Stags, later the Chicago Bulls, lost to the Philadelphia Warriors in the first NBA Championship. The Warriors recently eclipsed some Bulls records...
Philadelphia is named from Revelation.
The square root of 49 is 7. 7 is the 4th prime. Revelation is full of 7 and 4.
Jerry Krause even has the '74' coding.
He also died a span of 33-days from Jordan's 54th birthday.
