Got bored of kicking everyone's ass. Figured it'd be more of a challenge to do it in his mid thirties. He figured wrong as he was still toying with the rest of the NBA a few years shy of being 40.
well, here is why Jordan did what he did:
His father's murder took a noticeable toll on his psyche and personal life. His and Father's earliest and first love was always baseball, and MJ made a promise to his dad that he would play in the MLB. He took it upon himself to work towards that goal, as a tribute.
His first half season was rocky, as people recall....but it was seen as more of a circus when you compare his prowess on the basketball court. The truth is that during his final half season with Birmingham and the summer spent in the AAA elite league (forget what this is called, but considered a major stepping stone for many on their way to the Majors), Jordan, astonishingly bumped his average from something like a .207 to a .275. He relentlessly worked on all of his batting mechanics throughout that season, and showed nothing but steady, consistent improvement. His strikeouts fell sharply, his OBP escalated, and even his fielding improved remarkably.
Those who actually followed his progress during this time couldn't really make a comparison to anyone else showing that type of drastic improvement. He was by any estimation on his way to the majors....then the strike happened.
People seem to forget this--he didn't go back to the NBA b/c he was failing at baseball; he returned to the NBA because baseball ceased to exist for a season. Jordan was, in fact, improving and succeeding in baseball at a level never before realized.
There was a 30 for 30 doc, or maybe a lengthy article that reflected on Jordan's time in MLB. Rather startling, actually.
Of course, then Jordan returns to basketball, completely alters his game, and manages to be even better than he was before. what the hell--guy was a monster.
