Centre, 2x rovers, 2x wings = 500 % tog
Most of what I’ve seen and myself have Hep, Shiel, Zaka, Merrett, Myers, Smith, McGrath, Langford and Parish starting and they all should spend most of there time through the midfield. You’d expect the avg. tog for them would come to 70-75%, maybe higher.
75% x 9 = 675%
So even if they share 100% of 1 fwd role which could be an extra midfielder and play 5 fwd. It still leaves 75% of time of filling either another fwd role or a defence role.
The more I think about it the less likely I see us playing a 7th defender as I think all 9 of those mids are better players then the 7th selected defender.
