I think at some point we have to accept that the players are simply good enough and no amount of tactics or wizardry will get consistent positive results with this lot. We started with a purple patch but there's been a lot of tape on how we play with an extremely limited bunch of players for a while, which has coincided with our downturn in form since the Bristol game.
That being said using J Colwill and Ashford would be a nice change.
