I've wanted Collins for a long time and would be happy with this deal. I love Smart, but am also pretty high on Romeo, as well. And with Pritchard's emergence, we have almost no use for Smart at PG when Kemba returns. In fact, I was thinking about starting a thread about how we should begin considering Smart a wing, rather than a guard...but that is another topic for another time.
I do worry about another team tossing a max offer at Collins this FA, but at least matching that max would only be a 25% max for 3-4 years with only 5% raises, rather than what we just saw with Tatum's extension. That is worst case scenario - it would never just be a rental.
So, yeah, let's find a way to acquire Collins while [obviously] keeping Tatum and Brown. I am game.
