Tomorrow we will see the game 3, let's see if they can still handle the Pacers without OG who had a huge contribution in the game 2 win before he got injured. And as per report, there's even a possibility that Bruson might not play as he was lited as questionable.
It will be a very hard task for Knicks to beat Pacers without OG and Brunson not only because of the home court advantage of Pacers but also they are already in close match when Knicks has strong line-up with the 2 players is active. I doubt that the current Knicks without Brunson can beat a solid Pacers.
I think Knicks will still face a difficulty beating Pacers in home court even with OG and Brunson in the court so I think they might use game 3 and 4 for regrouping then focus on the remaining games until their starters come back.
Let's wait until the actual game starts. Because I am not sure with all of these reports become a tactic for these teams to make their rival confident that if one of their stars aren't going to play, they will have an advantage. I am not really sure but it seems that it's sort of a mind game to me until the game starts and with that rumored player won't be playing actually entered to the first five.
