Ariza and Tucker and Anderson need to step up. We have enough to sustain one loss of a wing for a stretch of the season. Losing two would be tough. Could see more of the Paul-Gordon-Harden lineup as well.
If it's a dislocated shoulder that worries me. Usually you end up dislocating it over and over again because it is never the same. Remember Carl Herrera?
I just went through a separated shoulder (AC joint separation grade 1). It kept me out 2 weeks then I played again cautiously for about a week. We would need to know the level of separation (1-5) before knowing his time table.
That was over 20 years ago - they know how to tighten that up better these days. Bigger issue is that he is going to be out for an extended period. Don't expect to seem him before April if it is indeed dislocated.
