Agree that this our biggest upgrade needed. Depending on who we get (hypothetically) this could really push us forward. The C's, when healthy, are a top 3 team in the East. With a notable upgrade over Amir they could make a lot of noise.
I still am dreaming of Nikola Jokic. It would take a lot though, as he looks like the big to keep in Denver.
There are a few buy low candidates out there that might not require our best asessets. Okafor could be worth it if the price isn't too high, as he has several years of his rookie deal left. Not sure he is the right fit though. Nuric is another guy who could be a buy low.
Or we could make a big splash and use some of those trade pieces we have acquired. Either way, an upgrade over Amir would go a long way for this team.
