Based on what history do you see this mythical length of time that we get (and stay) healthy... happening? 10 or so games under .500 in the Western Conference is time to start thinking (and actually planning) given what we know about Zion.
If the other guys get healthy we can maybe right the ship without him and back into a play-in... But at this point - Who cares?
They are not contending until they can get a modern, reliable, and talented 8 man rotation... There are some young pieces here, but This ain't it... time to move on while guys like Zion, CJ, and BI are worth trading.
I've been saying for 3 years - we should build around BI and trade Zion... Not because BI is a better player or some beacon of health... But because compared to Zion... He's at least a more available piece you can build around.
