Lewis needs a rest coz the lad is at uni alday doing his sports course, coming to training on thurs ad tue evenings and when your a young lad working your arse off allday and all night your body sustains some fatigue, a rest would replenish his levels and get him going again like he was last year
A fit 21yr old lad shouldn't need a 'rest'!! If he is to go on to bigger and better things (which is very likely) will a club in the Championship or similar give him a rest 'cos he's playing every week, and training in between? I don't think so.
Nearly all the players have full time jobs, some harder than others maybe, AND train on a tuesday and thursday too, I'm sure thay would love a rest to replenish their levels, but come Saturday afternoon they have a job to do and they go out and (try to) do it.
However, if a player felt they needed a rest, they could speak to Graham about it. I'd love to be in the room to hear what his reply would be!!
