Agreed. Nobody thinks Davis is anywhere near as good as Maravich. Maravich was an NBA star (3rd pick in his draft, 5-time All Star) whereas Davis will not likely even sniff the NBA. Literally nobody is making the argument that Davis is better than, or anything close to, Maravich as a talent.
The general point that I'm trying to make is that - if Maravich was playing as a 19-21 year old today - he himself wouldn't score 3,667 points in 3 years. Because the era is so totally different. Teams play like 35-40 fewer possessions per game, and they actually play half-court defense (which makes scoring more difficult and partly why there are so many fewer possessions). And teams are better equipped to limit a single player in ways that just weren't in practice 55 years ago: defense is allowed way more contact, teams play smarter offense, which prevents a lot of the fast breaking that went on back then, and teams gameplan and are coached much better now. There is also way more depth of talent and way more opportunity balance, there is less of an opportunity for a single player to totally dominate his team's possessions on a major conference team. It's just night and day in terms of what basketball looks like now compared with back then.
Just factoring in the differences in pace of play would knock Maravich's 44 ppg down to ~29-30 ppg. And then you factor in tougher defense (WAY fewer fast breaks), more talent balance (unless Maravich went to play for a low-major school), and Maravich might have averaged 25 ppg as a freshman in today's game. And that's even accounting for the lack of a 3pt line.
Maravich was a great player, absolutely no question. He was a 5-time NBA All Star and Hall of Famer. But his 44 ppg average was very much a product of circumstance: playing on a terrible team with his dad as coach and in an era when teams took tons and tons of shots.
