Van Gundy's are upping the ante on the Heat. Doing it on purpose.
They want all the pressure, all the attention on the Heat ALL year.
If they just say, "hey, they're loaded, they are going to be a real threat in the postseason" then that's it, it's done, end of story. No pressure gets added, no one on record stating what the Heat could do, just that they are solid and a threat to win it all.
By adding all this legacy, MJ led, 73 wins record, they are making each and every single game in a sense, a must win (they'd only have 9 give away games they could lose if pursuing the record over the course of 6 months.) putting a bullseye squarely on the Heat's chest. Let's say the Heat lose that 10th game mid March, everyone starts proclaiming it a "wasted" season, a failure, all the attention and focus is on that, and NOT on just winning the championship.
Meanwhile, Stan and the Magic lay low all year, win their 58-60 games comfortably behind the Heat, nobody will talk about them, nobody will ask questions after a meaningless loss in January on the road "what's wrong with the Magic" and the like, and come playoff time, they'll be ready and know what they need to do to make a move. It's a win win for the Van Gundy's to play this angle.
It is gamesmanship at the highest level. Make no mistake, Riley was a master at it, and he is doing his best to circumvent everything that the Van Gundy's say with his team to use it as motivation. I wouldn't put it past Riles to start hackin peoples twitter accounts and leavin nasty messages on the big 3's twitters.
This season is going to be phenomenal.
