Agree completely. Tyler Hero is still pretty young... a year younger than Marcus Carr is you can believe it. Here are some comps of players at a similar stage of their career.

At the same stage, Herro is a better shooter than most of the players on the list and led the entire NBA in FT% this year. His is great in crunch time. He rebounds at a high rate for his position and has underrated athleticism. He turns the ball over at a low rate and doesn't foul. He gets buckets without dominating the ball (see his 25.6 USG).
I really think he would be a fantastic piece for Portland to build around alongside Scoot. But if I was Miami, I wouldn't give him up for Lillard's bloated contract.
