I hear you. Sure, giving some weight to trainig at 'practice' will make it easier to get rookies off the ground, but the value to training in practice vs. in-game can be weighted, and anyone relyinig on practice for fulling training would still come up short. Unless BB is going to roll a development league for players in higher leagues to use for rookies, the higher league managers have to use the TL for almost all starting-caliber players and even most of the key bench players. And unless we start seeing Wembayama-type rookies who are drafted with 95+ TSP, it's always going to take a bunch of seasons to get even the best rookies ready for a high-league starting lineup.
I also agree with you that salaries are a bit wonky. Why a player that happens to have high Rebounding gets a big salary boost doesn't make a tone of sense when other skills seem to have less of an impact on salary. Nevertheless, I personally still traing Rebounding a good deal and know that I need good rebounding efforts to win games, and I personally have never make training decisions based in the impact on salary. In fact, we'd be seeing more players on the TL with skills at those positions that impact salary disporportionately if most managers trained based on salary impact since they'd be dumping that players the most to cut payroll, but we just don't see that. Diving and Handling aren't skills that drive up salary, yet those ore the most common high skills for players on the TL with at least 102 TSP that i see.
In the end, I don't see making rookie-traiing a little easier as such a terrible thing, I don't think the of 'easininess' can be kept at a minimum. Maybe practice-training isn't the solution, I'm just looking at the results of where'we're at right now looking for a path towards making it more likely that we'll see greater diversity in players, and a greater diverty in paths towards success for managers. The training system goes back to the begining fo the game (I kinow, I've been playing this game for a while). The NBA was still featuring drive and dish players (like the young version of Chris Paul), and big centers who could plug the lane on defense and score in the post were still valued back then. Players salaries have been getting tweaked regularly over the years, but I just think it's time to finally think about how to improve one of the most impactful parts of this great game that's never been even tweaked based on observable outcomes.
