Fair play and fair matches

Ive looked at the rules and I wonder if someone could clarify a thing or two.
Ive made a player whos best stat is a 77 (All rounder) however he has 72 on both FH and BH.
From looking at the test tournament it seems one side can be 79 but the other wing has to be max 69 or less.
Is this correct or would this be ok ? If I have to recreate, of the +5 bonus how many would I put to my favoured side?
Specials are approach expert and wrong foot expert.
Cheers.
