1. The teams that won did not suffer significant injury to their pgs. That's why then won.
2. Most of the teams that won had adequate backups pgs, which is one reason why their starting pg stayed healthy. You mention Shaw, but Jordan Farmar is an excellent backup and would be starting on most teams in the league. Jacque Vaughn (Spurs) and Lindsay Hunter (Pistons) were also solid backups.
If Farmar would be starting on most teams he'd be starting on the Lakers. Fisher's a below average starter.
Well, Fisher's talent may be below average, but his brain is way above average, as is his ability to make clutch shots. Once again, talent is overrated. What matters is production: the ability to make plays when you need them.
Even so, it is qwuite possible that Farmar will be starting for the Lakers within two years, assuming that he stays healthy and continues to progress. IMHO he is better than alot of guys with bigger names, starting with Felton in Charlotte, who isn't worth close to the money he's been demanding.
So insteads of scrambling around at midseason trying to fill the void if Rondo goes down, the Celtics should be looking to fill that vacancy now. In addition to the guys on Nickagenta's list, I would be asking about Sergio Rodriguez, Roko Leni Ukic and Rudy Fermandez (where are his minutes not that the Blazers have Miller, Blake and Bayless?).
Sure, all of those players have flaws, but they have strengths as well.
