Nothing to do with not rating him, I love the bloke and have been calling for him to be played the last 4 years, but they need to re-jig the midfield and he's the only one of worth there at the moment. We won't get anything (and probably can't) trade Douglas and Mackay and Thommo is likely to suck up a lot of minutes again anyway.
Thommo would be licking his lips at Lyons leaving, pushes him a spot up which leaves him only having to remain ahead of CEY, Wigg and Grigg. And it's doubtful that all 3 will remain. It's a genius move to keep Thommo in the best 22, force out players in front of him.
