This trade would not surprise me but it would frustrate me and remind all fans that a teams window is shorter than we think.
I'm not saying that the Nets are guaranteed to come out of the East, but I am saying that the league can change so much and just when you think your team is ready to take the next step, other teams can leapfrog you. There will be decision times in the next few years. I don't think the Cs are facing "now-or-never" decisions yet, but there will be. Hopefully when those times come, the Cs can make the necessary moves/advances to take their chance during their window.
