A lot gets made of 'stars' but at this point winning or losing will be a team effort. If enough of Smart, Grant, Horford, White, PP etc step up, make shots and not turn the ball over, they win the title. If not, they don't.
GS strategy is to keep Tatum away from the paint as much as possible and he's constantly being guarded by smaller, quicker guys who are looking to strip/pressure him and cause TO's. The answer is him moving the ball, trusting his teammates - but most importantly those teammates knocking down open looks. Do this enough times they'll be hanging banner # 18 next fall.
All of them went ice cold when it mattered last night - hence us being at 2-2.
