I mean first game, we started:
Conley, 1 time All-star, age 35
Clarkson, SMOTY winner, age 30
Lauri, All-Rookie team 2018 and starter in Cleveland, age 26
Jarred Vanderbilt, starter in a playoff team in previous year, age 23
Kelly Olynyk, played 23 MPG in NBA finals 2 years earlier, age 30
Is that a tanking team? Average age 29.
If Lauri wouldn't have exploded the way he did, then yes, that is likely a tanking team.
