This may be a 3 year window but I think the general opinion is for an experienced team this season is our best chance to win a ring this season as opposed to the next 2 years.
Weren't we going into this season excited about STAT and company having a full camp and then he misses the first 30 games? That type of bad luck is bound to happen more than once for an older club like us. So I can't just assume we will repeat our success next season without any major setbacks.
We may get better health wise but I think this season is our only chance to really win a title for the next 3 years, especially since the East is so vulerable with a lazy HEAT team, Bulls without Rose, and the Celtics/Pacers/Sixers all dealing with huge problems.
