When that 1-dimensional finisher is significantly better than your guy, yeah that's a trade you make. You're banking on Reinhart becoming a 70 point player but there is no guarantee that will happen, whereas Laine has done that before. Its backward logic used to downplay Laine when it's not even comparable. He is a top 2 pick who will be 24 for essentially the entire season, how much progression is left? History tells us that those kinds of players peak in their early 20s, and I don't see Reinhart being exceptional enough as to flip that trend.
Honestly I don't even know why I'm arguing this, its clear you have strong (wrong might I add) opinions. Laine is better than Reinhart and very very likely will be his entire career.
