Johhny, it's not URB mods problem, it's NBA 2k14 games problem, first 2 seasons is crashing always, sometimes only in next season, sometimes in first also, but i found solution, and it's working. Tested on steam. Non - steam i dont test, but think still need to work.
I will tell what i did in steps.
1. Clean install - after that download all parts from urb 2016/2015.
2. Make sure to use roster finalurbmycareer2016, if you using not mycareer roster it maybe wouldnt work. before start your career load roster.
3. Then start creation of your player, i suggest to use Pg because in nba 2k14 other position is so boring, and PC in PG is so noob.
3. When you are inside creation , dont continue to rookie showcase before next step.
4. Find in google cheat engine, and use cheat engine table "NBA 2K14 Cheat Table V2" in google seach for it.
5. open and load your nba2k14 game in.In table find where is "Games in season" - change value to 0. That will give you only 14 games in season. lock it by checking with x.
6. after that, go all way down to find "other options " draft position - change value to 3 . Lock it also. This will you draft in NY knicks i think you wouldnt mess up with team questions

.
7. Then when you all checked an ready continue creation and go to showcase.
Need to use - "next key game" in first 3 seasons to skip games. I always using next key game, because 20 games in season is ok for me already annoying, i dont play all games 82, i dont know what will happen if you choose to play all games

but i didnt get crash at all with no one team.
Change value "games in season" to 3 only when you passed 2 rookie years i would suggest only after all rookie years, and when you could choose team. In 90% you wouldnt get time to play, you need to be ready to skipp 3 years without any points and minutes and money, but after 3 years you will play this game without crash, tried already think 4 careers. 2 pg used more then 5 seasons. no crash.with that table you can give SP and atribute boost, and you wouldnt loose anything , just sometimes, you loose good playing time with our stars, because, they will be traded to other teams.
you can change games in season only offseasons and in playoffs, if you will change it in current season game will crash.
by the way, i dont know what happened, i changed jerseys but problem not solved with grizzlies jerseys. noone have this problem?
i think i found the problem, tried to play now with different jerseys for grizzlies, all worked fine, problem with that home and aways newest jerseys, can you tell me name off this files , what need to change?
you need to check out that grizzlies problem, i changed files, but still working only some not all jerseys.
EDIT - OU YEEE>> FIXED, that problem was in cloth files i think, or maybe not all files was upadated from firs 4 parts, but now it's fixed

i dont know why other teams was ok only grizzlies had problem.
