It's too early to consider moving on from Canales, but replacing Bryce is long overdue.
Bryce believers say that he thrives in improvising, but so far we've seen nothing but disaster when he improvises (interceptions, fumbles). I think that's why Canales is telling him to stop playing hero ball. With that out the window, he doesn't have the skills or abilities to compensate.
I like their madden analogy. It perfectly explains Bryce.
