This has been a trend for years now. I remember Dean Colton being one of the first Dons' wingers used in this way.
I believe using wingers in this role does spread the workload better. I've never seen a winger look too knackered to do a forward run when getting the ball on the wing in an attacking position so I don't think it compromises their effectiveness. I'm sure this tactic helps save the energy of the middles for doing the hard tackling, which must be the most draining part of the game.
We played down the middle a lot today. I think we overdid it. We didn't move the ball wide enough, quickly enough which is why Olly and Bag of Bones Halliday didn't get the ball enough as attacking threats. I think it's our present style of attacking play that isn't utilising our wingers' strengths, not the fact they're driving the ball out of defence.
I must say that the tactic of running the ball towards the corner on the sixth tackle, rather than kicking into touch, when near the opponent's line is a really good move. Making teams drive it out from there is tough. It's much better than giving them a tap restart in the middle of the field. Coventry were lucky to get near the halfway line by the sixth tackle on many occasions and their sixth tackle kicks were mainly collected by us in open play 20 metres from our line, giving us an easy way out.
