The best example you should look back on is the bulldogs. They signed Kikau, Mahoney, Addo-Carr and Burton which could arguably be worse than the Tiger's signings you listed however after the Crichton signing they immediately improved. This is proof that big name signings arent going to immediately change a teams entire identity. The rest of the team was still poor at the time with the halves being a horrible fit to the team, but with the rejuvenation of both the teams halves and backs with the development of young players, this offseason was marginally different to the time we had made those signings.
