So ya, if you go back a few years to June/July 2017, and I tell you by 2021 Crowder has 2 Final appearances, Abdel Nadar is in the Finals, Kelly Olynyk made the Finals (last year), you'd probably feel pretty good about the C's chances.
Heck, go back to 2012, and I tell you in the next 10 years that Rondo gets another ring, Avery Bradley gets a ring, and E'Tauwn Moore wins a ring (we'll see if this comes true this year), you'd be ecstatic. I know I would be lol.
