It's worth noting that Booker was showing a great performance before the injury as he scored 31 points in just 25 minutes. So I think he could have made a decisive contribution in the 4th quarter, and the Suns could have won if he hadn't got injured. Let's hope Booker doesn't have a serious hamstring injury. Otherwise, the Suns may have big problems in the upcoming matches.
A tragedy like this always happened in the NBA playoffs where a star player will not gonna make it because of certain injuries that are why when you reached the finals you need to give everything you've got to win it because of the chances to get back there are almost impossible. The reasons are multiple and most of the time the other teams are also improving and will gonna easily beat them if they missed one star or role key player in the team. I think this has happened before when Chris Paul was about to beat the GSW when he was at Houston and now Booker is unsure to come back to play in the game 3.
