The Brown appointment was a big call for Saints as whoever was the new coach had to start again and rebuild from what Potter and Royce had begun to start.
Given that, I think he's already showing why he's been a good appointment: he's made a few big selection calls and they all seem to have paid off.
Lomax at FB - was forced into I suppose, but he still had to move him from #7.
Wilkin moved into #7 when he could have easily stuck with Lomax
Percival was a massive call last week against the Champions and he was arguably our best player.
Walker and Greenwood have been tried and their selections paid off last night as defensively they were good.
Hohaia being picked over Gaskell for last night was a massive call and that also seemed to pay off, he was good.
Would Royce/Rush etc done the above? Hard to say but I doubt they would be willing to test the whole squad like Brown is doing at the minute.
The big test comes at the end of this year as we will basically need a new front row. We will see whether he can spot a player or not.
