Basketball isn't a difficult game. HOU with Hakeem basically ran off the same principles as BOS except they got there a slightly different way. BOS uses it talent advantage to get a matchup it can exploit to generate defensive help and then throws the ball all over the place to find the open shot.
HOU would throw the ball to Hakeem, who was basically unguardable, surround him with shooters, and let the defense decide if they wanted to help and give up the open 3P or let Hakeem get his.

https://www.reddit.com/r/nbadiscussion/comments/169zwbt/could_the_95_rockets_have_kicked_off_an_early/ - says HOU led the NBA in 3PA in 93-94, 94-95, and 97-98. Plus they played Horry a lot at the 4 - really the first modern stretch 4 (as pointed out by the article).
Every team does this - get to a bad matchup, force help, and then find the open shot. It's just that BOS has the best shooting starting 5 in NBA history so a lot of their open shots are going to be 3Ps.
