Honestly mate. I think it's obvious that you're doing a good job managing you team, but your players havent had the development time to be as good as the rest of the division (plus unlucky in the cup). You're training well (those OD pops will come and it's generally assumed that OD training is slightly slower than the others, as (in my opinion) it is one of the most important and influencial.
If i were you, i'd take the relegation, take the number 1 draft pick (which might be worth more than staying in the division anyway), and re-group in DiV for the next season. You'll feel happier as you'll be winning, you'll have easy minute distribution becuase of it, and when you go back up, you'll be a hell of a lot better.
PS. the 1st game you lost due to low inside scoring (and possibly eth differnece)
lol the 2nd one is the same but i looked at your games and you got beaten becuase that guy has a lot better team than you. He neutralised your attack and you played the wrong tactic for his outside game.
Anyway mate, good luck
