The 2017 draft class has been hyped as one of the strongest in years and so far I think it might be true.

This year the draft class has been said to be one of the deepest ones in years before most of these players have even played a game! I thought a lot of the hype had to do with the general age of the draft but the summer league is showing me up with my opinions very early on!
As I mentioned earlier the summer league is still young as we have only seen some teams in action. However, the games I have seen the players who were actual draft picks whether it be the first or second round picks have mostly looked NBA ready and a lot of these guys are still really young. I just finished watching The Celtics with the number 3 pick Jayson Tatum vs The 76ers and their number 1 draft pick Markelle Fultz and I must say I was blown away by the talent. The other games have not seen as many other 1st round lottery draft picks apart from Jonathan Isaac who has also looked very solid.

I have not even seen a big enough sample size to make a real decision but I am really excited for the future of the NBA when we have young teams forming and grooming players in a way the League hasn't really ever seen before. This I will call it "Process" that teams are doing in the time that they know they can't compete is a strange step but it seems to have good long term plans and it now leaves a fan like me extremely excited to see what the future holds for these young "mini-super teams"!
