Only if exaggerating a chronic condition/resting 95 games over 2 seasons, successfully tanking his value to such an extent that the team he was eventually "traded" to was handed the league's most complete, having the overwhelming favorite decimated by injury and still barely eking out a tainted championship, is what you call "bounce back".
Harden at least showed up to work. He didn't hide across the country while his sleazebag uncle attempted to destroy the hard earned reputation of his current employer, nor withhold medical information from said employer paying him $18.6M or say he'd only re-sign in one city, leaving them only able to recoup pennies on the dollar.
