Lever/Frost/OMAC can definitely all play together
Lever can phase out Lewis' position, as people forget that he's incredibly nimble and clean for a taller bloke, I even remember there was some talk that Lever could play through the midfield in his draft year. Let Frost and Omac take the big boys and Lever can play on the 3rd tall, spare, or on a HBF. Although he started slowly, some of his play before he got injured was mouth-watering
Reckon Lever replaces the role Fristch is currently playing and Fristch goes back up the ground where he is more dangerous
