The NBA prevent Offense, why do teams walk it up in close games late........ Ridiculous.........
Because it's awesome strategy to let the tired defense get set and waste 13 seconds of your shot clock? On a side note, once you start seeing one team go to this garbage in the 4th... live under bets.
One team, they both do it.......... Mind boggling.....
Right. Once one team does it, the other realizes "it's time to get serious!". And starts the shitty offense.
