Given that for some inexpliocable reason Lid's trade value is so low, I've changed my mind and say keep. Plonk him at FF as a full time mid size fwd and Im sure he can play another 5-6 years.
The fact Griffiths as a 29 y/o was traded for a lot more than what industry expects us to get for Lids is rubbish. Only way Id consider it was if it was for a big young talent oir a couple of late first rounder/early second rounders.
