To be blunt your team just isn't good. You may have the same average rating, but what I like to do when comparing teams on paper is to look at the average ratings minus WE and DU, because they play no factor in the outcome of the game. While you and Gwynedd-Mercy have the same overall rating, if you take away your 19 point edge in WE and 34 point edge in DU your team's average ratings in categories that matter in the game is 53 points lower than GM. Your team also is very unathletic and slow, even for a D3 team. You don't have 1 player with a 50 athleticism and only 1 player with a 50 speed. While GM has 5 players with a 50 athleticism and 6 with at least 50 speed.
Take a look at my team, and compare it to yours. My team's average athleticism is 56, 8 of my 12 players are over 50 with 3 guys over 70. 7 of my 12 are over 50 speed. Half of my team is made up of players that have both 50 athleticism and 50 speed.
Your team is also weak on the boards, you have a team average of 28 and only 3 guys over 40. I think the areas to focus most on to begin building a good team is atheticism, speed and rebounding. Passing, perimeter and free throw shooting would be next then defense, ball handling, LP and shot blocking.
