I actually reckon its gotten harder for teams to rent a team for the playoffs and actually win it all. Firstly they sacrifice HCA, which as we all know, is huge. And second, alot of teams now have good wage efficient players, which aren't that far behind the 300K wage monsters (for example, from my team Manfrotto has more total skill points than a Radford, they are just allocated differently
).
5 or 6 seasons ago the 300K wage players were still cheap, and probably a good recipe for short term playoff success. I'm not so sure that is the case now.
