I think the squad is mostly unchanged due to a preference for team unity, cohesion, spirit, and all that lark. Lets face it, the likes of Keogh, Miller, Long, etc. are only there to train with the starting team. Maybe this group of lads gets on really well? We saw the togetherness in the last game against Georgia. I think it is always good to get a come from behind win and I don't think that teams who are not united get them.
Yes there are some players out there who are technically better than the reserves in our squad, not the starting 11, but I think Trapp sees it more like a club. We just need 1st or 2nd when the fixtures are over and he is reluctant to change it.
