1. "up to"
2. Different teams value different players differently. Maybe (MAYBE) the Nets value Anfernee at "up to" 3 FR picks too.
Yeah, doesn't seem likely, but a man can dream. I mean, if you were an expansion team (and the Nets essentially are right now), wouldn't you go for Anfernee over Bridges? I mean, Bridges is obviously BETTER, but he's not better at scoring-in-bunches and looking spectacular. Bridges is essentially an elite role player, whereas Anfernee is a poor man's star.
Sidenote: if I were the Thunder, sitting on approximately 6 squillion picks, I'd be seriously tempted to swoop in for Mikal. Hell, offer 4 picks, why not?
