Agree on Pekovic, though it's worth mentioning he really didn't suffer from any injuries in the game. His decline was completely independent of injury (though that likely won't be the case in real life). I've raised potential for many, many guys before (with no success) but Pekovic was the only one in the above images so I mentioned him.
To be clear, there are plenty more where the above images came from, the guys above were just the first ones I came across when doing a quick scan of the league, and were all the appropriate age. They have regressed exactly like every other player has; 3-4 overall decreases every single year they start to regress.
Vasquez, Wolters, Green, Shumpert, Mack, are absolutely not "past their prime." It's not reasonable to expect all of them (or any, really) to further improve but for
all of them to be completely out of the NBA at or before age 30 is a bit silly, no? Especially if you consider all of the other guys (and everyone else of the same age that I didn't bother to include), it's nowhere near realistic. Even Pekovic, I agree he won't be a starter in a few years but guaranteed out of the NBA?
I forgot to mention, the reason I even did this scan in the first place was because I had noticed that, except for a few teams with stacked decks, every team in my league was horrible (~70 overall). I looked around to see if the computer generated players were all
that bad (I've lowered draft quality to be closer to real life), but no, there's just a complete lack of veterans.
I'll probably go through and try what you've done--apply potential changes to everyone. It's going to stink because I've loved getting to use Beds' updated official rosters but if there's any chance it brings things closer to normalcy, it'll be worth it.
