And it would appear the player who was SFMC was severely limited by his team, you can only do so well without a team to back you up.

If you take all the ranks and assign them arbitrary numbers from 1 to 18 corresponding to the rank (1 - Silver 1, 18 - Global Elite) and add up the totals for each team in your case and divide each by 5 to get an average rank the enemy team had an average rank of 13.2 (~MGE) whereas your team had an average of 14.4 (~DMG). Therefore *technically* your team's average rank was higher.
