Yes, but I would argue it was more than that. Stats only give you so much information. My perception is that the bigger the game, the better Bowns gets, I would say that this was not the same with the Moose. He gives up a LOT of rebounds, this means that his D has to operate in a very specific way and he is often called to make multiple saves which bump up his stats.
I am not arguing that he isn’t a good NM, he is (although I would always take Bowns first), more that he is not the answer to the problems Sheffield have
