Kalani's pre-game locker room speeches and post-game comments after AZ and WI focus on how hard the team worked on strength, conditioning and nutrition during the off-season and camp. There are solid motivational reasons for the statement, and possibly some self-congratulatory, told-you-so reasons, too. But Kalani seems to genuinely believe they did better than most if not any other team in off-season S&C/nutrition, and slugging it out in the trenches with Wisconsin is pretty solid evidence.
Even allowing for a large amount of coach speak, it appears the fans and media completely missed this development over the last six months. I don't recall anyone noticing--much less being impressed with--S&C and nutrition. If anything, there was a consistent undercurrent of criticism about and occasional outright derision for BYU's S&C/nutrition programs.
So is Kalani just overstating or did the media & fans completely whiff on this emerging story? As usual, I suppose the truth lies somewhere in the middle.
