Only thing I would like to add regarding the sub is that I think it is better suited to a more senior player who can more easily read/adjust to the tempo of the game, for no other reason than they have experience behind them. IMO a young 5-10 gamer ( or player coming from a long stint in the WAFL) coming into the derby last week would really have struggled to make any impact, due to not knowing how to adjust to the pace and pressure.We don't need the sub to be the difference because we've usually got the game won already by then.
But seriously, what are you suggesting exactly? That we should start returning 'underdone' players on the field and save a 'better' player for the sub just in case he manages to turn the game later?
Wouldn't that fitter, match-hardened player have more chance of turning the game if he was out on the field for its entirety?
I'm presuming a structure and effort driven coach like Lyon would prefer to put an emphasis on a whole team effort from the 1st bounce to win games rather than subscribing to the notion of a super-sub.
