In the minutes Kyrie has been on the floor this year the Celtics have won those minutes 25 times, lost 7 times and were tied twice. The team as a whole has lost 14 games that Kyrie has played in. Yes that is correct the C's have lost Kyrie's minutes only 7 times yet somehow have managed to lose 14 games that he has played in so far this year.
If you throw out the first 6 games of the year when Kyrie was still trying to get his sea legs under him the C's are 22W-4L-2T in his minutes, of those last 28 games, and yet somehow the C's lost 12 of those games.
On the year so far the C's are +235 points in Kyrie's 1099 minutes played. In the 745 minutes Kyrie has not been on the floor the C's are +2 points.
Kyrie on court net rating +9.1 (would rank 2nd in the league if this were the C's total net rating)
Kyrie off court net rating -1.0 (would rank 21st in the league if this were the C's total net rating)
With Kyrie on court this year the C's have produced a TS% (true shooting) of 58.0% which is a number close to what contenders put up in recent years and would rank 3rd in the league behind G.S. 58.9% and Milwaukee 58.5% this year. With Kyrie off the court the C's TS% is 53.9% which would rank 25th in the league this year.
Conclusion is that every ounce of evidence says that the C's are under performing when Kyrie has not been in the game, to blame Kyrie for the struggles this team has endured so far this season is nonsense. This team will be a juggernaut when Hayward gets fully squared away, the injury bug alleviates a little and the youngsters settle into their roles. Kyrie is vital to the success and title contention for this team. Stop looking for someone to blame erroneously and just enjoy the ride.
