go90 did a 10 part document-series called "QB1" following the senior year of Tate Martell, Jake Fromm (now at Georgia) and Tayvon Bowers (now at Wake Forest). Real in depth look at their lives, their up bringing and their practices and games. It really tells the nitty gritty details and you get great insight into their personalities.
I highly recommend checking this out if you haven't already. Link to the first episode is posted above. Most installments are about a half an hour.
