31 according to my cavs coworkers in Ohio. They guarantee Kyrie will be injured and they also said he cannot csrry a team and had a horrible win loss without Lebron playing.
This is actually a really important point I hadn't considered until you mentioned it.
Here are Kyrie's games played so far in this career:
2012 - 51
2013 - 59
2014 - 71
2015 - 75
2016 - 53
2017 - 72
Looks like it's about a 50/50 shot that Kyrie plays 70+ games instead of missing 20-30 games.
If Kyrie misses 20-30 games, on top of Hayward being out, the Celts are going to be in trouble trying to make the playoffs.
Luckily Al Horford is a relatively healthy guy. He missed 14 games last year, but apart from his pectoral injury that wiped out most of a season, he's been pretty durable throughout his career.
Even assuming a relatively healthy season from Kyrie, it looks like we should expect him to miss about 8-10 games. The Celts will have to rely on Jaylen Brown and Jayson Tatum to lead the team in scoring in those games, with no traditional point guard to set them up.
It's going to be tough.
