....The league had already seen Mikan and Chamberlain change the game at C. ...Honestly, I'm not so sure Chamberlain revolutionized the game, so much as he dominated. Mikan forced the league to widen the lane and outlaw defensive goaltending. He also had a lot to do with the implementation of the shot clock. He didn't dominate in the same way Wilt did - his career EFG% was something like 40%. But when you force rule changes, and even the dimensions of part of the court, you've revolutionized the game. (The change to the width of the paint was known as the "Mikan Rule")
I think you made a mistake about Mikan. He wasn't the one who forced the lane widening. According to NBA.com's "Appreciation of Wilt Chamberlain" Chamberlain is the reason the NBA's foul lane is 16 feet wide. It was 12 feet when Chamberlain entered the league in 1959, and the 7-foot-1, 275-pounder captured both Rookie of the Year and Most Valuable Player honors by setting up shop in the low post, then using his strength to lean in on opponents and lay the ball in the basket with his soft finger-roll.After five years of watching Chamberlain score virtually at will, the powers-that-be added four feet to the width of the lane to make it a little tougher on him. Chamberlain responded by perfecting a turn-around jumper.
Chamberlain is responsible for changes in rules as well as court dimensions. When he was playing college ball at Kansas, his teammates' favorite play was to lob the ball toward the basket, hoping simply to get it in the vicinity of the rim. Chamberlain would roll to the hoop, catch whatever came within his enormous wingspan and slam it home. His rivals couldn't stop him, so the rules-makers outlawed offensive basket interference, preventing Chamberlain from touching the ball in the cylinder above the rim. That rule remains in effect to this day, in both the college and pro games, though it is widely ignored in today's offense-starved NBA when it comes to alley-oop passes, many of which are caught in the cylinder.
Rulemakers also banned the practice of lobbing the ball in from the baseline directly over the backboard so a player — read: Chamberlain — couldn't catch it near the basket in position for an easy score.
I think Chamberlain also was responsible for the rule that says a player cannot dunk a foul shot. He was a notoriously bad FT shooter, so he tried taking a couple of steps from behind the FT line and jumping to dunk the FT. (Long before someone started doing that in the slam dunk contest). That was banned almost immediately with a new rule.
