Point was, the Clippers and Mavs historically can't get to the promised land, with the exception of Dirk's 2011 squad, and tend to fold in the post season. It was a matchup of two perennial losers <-- the point. Show me a team that been to the playoffs multiple times that hasn't lost a series when being ahead.
I thought Thanos was supposed to be smart. You're goofy and sweet all rolled into one adorable character.
But what I really want to know, more importantly than your lack of knowledge of the history of basketball, is how Tony Stark easily yanked six infinity stones off your hand without you even noticing at the conclusions of EndGame, when a whole team of people, including Iron Man, couldn't do the same thing in the previous movie. I find that perplexing.
Stick to your strengths. Perhaps you were googling basketball facts when Tony did that?
