I do agree with you gun on the part of many older players would have a hay day on todays no touch foul system. Some could have scored a ton more.
Worthy for example was a career 17 and 5 guy and never had a year of more than 21 and 6. But IMO, under the current rules, Worthy could be a 28 and 10 type of player. He was a really, really good player of the 80s and 90s. But if he played now, he'd be a top 5 player in the league.
Now take a guy much less heralded from that same era - say, Ricky Pierce. That guy was a career 15 ppg scorer with a handful of seasons between 20 and 22. IMO, he'd be close to a 30 ppg scorer in today's NBA.
I can only imagine what guys like Mitch Richmond, Dale Ellis, Drexler and Wilkins could have done to the league under these rules. Holy cow.
