Especially with the way Woodson will likely coach and style our team. I agree 100% -- we need miracle/tons of help that's out of our control.
I wouldn't discount the potential impact Nash can make for us, though. If every single thing breaks are way:
*we get Nash for a bag of balls, and he performs like he did last year
*Lin becomes a clutch, all-star level player
*Shumpert returns as a top defensive stopper with some more polished offensive game
*Novak repeats the amazing season he had last year
*Amare plays like the Amare we got when we signed him
*Melo plays like prime Melo + added maturity
*TyChan stays healthy like he did last year (nobody likes to mention anymore how injury prone has been for a lot of his career)
If all of this happens, and Woodson coaches to his absolute best......I'd think we'd have a punchers chance, assuming MIA also does not continue to make improvements (eg signing a healthy Ray Allen).
If we don't get Nash, it's equal parts hubris and naivety about just how good Lebron is (which has been the case for yrs); and over-estimating our players relative to other top teams, without banking on major things breakning our way (re: Melo and Amare playing together, Amare playing like Amare, and Melo....not playing like Melo).
