Well, back in 2012-13, Draymond Green was the same age Maurice Harkless is now. He averaged 2.2 ppg. 3.3 rpg, 0.7 apg with a PER = 7.1. He shot .327 from the field and .209 from 3-point range. He flat out sucked. NOBODY envisioned him becoming the player he is today. He was a 4-year player at a major college program and still wasn't close to NBA ready. He's shown significant improvement every year. He didn't go from shit to superstar overnight. Anything is possible. Players do improve, some much more than others.
Back when the NA was gaga about drafting players like Kobe Bryant, Kevin Garnett and LeBron James right out of high school, the "conventional wisdom" is that 4-year college players had almost no potential upside. They had already reached their maximum potential. Players like Damian Lillard, C.J. McCollum and Draymond Green have all proven that wrong. Will Mo Harkless, with less real experience than Draymond Green, follow a similar arc? What about Noah Vonleh? Probably not, but who knows and who knows who else we will acquire in the next four years. To just give up and assume the worst seems futile. What if the Warriors had given up on Green after his abominable rookie season? Again you just never know.
We already have two young players that have shown vast improvement and averaged 25 and 20 ppg over an entire NBA season - no small feat. Crabbe and Harkless, if he can improve his shot, both have the potential to be very good 2-way players. Aminu stepped up big time last year in the playoffs for Dallas and again this year for Portland. Is he Draymond Green? No, but he was a valuable two-way player in this post season, especially in the GSW series. He's still young and on a cheap contract. Will he continue to improve? It's likely. His 3-point shooting went from a liability to above league average during the regular season to near elite level during the playoffs. I don't think he's reached his full potential, but also don't know what that potential is. Given his success and earning a role as a full time starter for the first time in his career, I bet he, like Mo Harkless, is highly motivated to work on his game during the offseason.
And then there's all that cap space, a positive winning culture, a savvy GM with a plan and a creative, respected coach players love to play for. To me, there is a lot more upside than downside here.
