Yes I agree, we are only 6 games in and opposition teams are getting there act together. Lomax and Richardson have done well over the first 3 games but lately it seems the opposition are finding a way to limit creative space more to Lomax than Richardson and hence limiting the service to Barba.
The worse thing that can happen is for Holbrook to start thinking again what is the best half back combination, in my opinion needs to modify his game plan to maintain composure when things go wrong.
