Looked up why I couldn't get the last 3 offline achievements I need to get only to find out that they were glitched achievements meaning they cannot be gotten due to a glitch in the game. These achievements are "Legacy Completion" which can't be done because you have to earn a lifetime contract with any team in legacy mode which is impossible simply because the programmers forgot to put a lifetime contract in the game.
Another one is "Single Game Individual record breaker" where you have to break all the records that were set by individual players in a single game like steals, blocks, etc. Its glitched because I guess the programmers forgot to put how many shots you have to make to break the shooting percentage records, therefore even after I shoot 100 three pointers for 100% fg percentage the record won't be broken. Same thing goes for "Team Record Breaker" achievement.
All that time I put into this for nothing when I could've been sold or traded it -_-. I guess it was just all-around garbage then. Oh well, its on Ebay now.
