Start seeing Sitake signalling in play calls which makes you wonder if he got more involved.
I still think Kalani took over, it was night and day difference and why is everyone pointing out Kalani was signaling in the second half but no one claims he was in the first. Tuiaki has stuck to his vanilla d too long for me to think a light bulb went off in his head at half that he suddenly abandoned his defensive philosophy and figured it out.
I definitely could be wrong.
