If SMB will continue that good defense outside like what you said the chance of winning is decent as we all know that TNT is really good when they've got the confidence outside, everything follows when the offense from outside is better, though shooters are shooters like Poguy, Heading and Oftana those 3 shooting assets of TNT needs to be well covered, else SMB will suffer since the defense of TNT is also giving them tough time to make a clear and easy shots.
That’s really TNT’s problem, they lack size, so they can’t attack inside with June Mar controlling the paint. On top of that, SMB also stepped up their defense, especially on TNT’s three-point shooting. So far, it’s clear that SMB is in control, and TNT’s big men are already in foul trouble. This series might not last long if it keeps going like this. SMB clearly doesn’t want a repeat of Game 1, they're out to finish this strong.
Ross is the game changer for this team if he will continue to play like that, and tnt shooting will not fall, its a short series last game optana struggle in the fourth quarter which is not him, since he always play better in the past series, so if they can't stop SMB since lacking of big man, if smb win this game its SMB will be the champion.
