Ian Book highlight reel
Book appears to be a “plus” in every category except height (and perhaps arm strength), although he doesn’t seem to be “elite” at any of them.
Given the right coach and team makeup, that could very well be exactly what a highly talented, but cap stressed team might want as a QB for a couple of years.
Book may very well be Coach’s backup plan. In case Winston kept throwing picks, in case Hill kept fumbling and taking huge sacks, in case Trevor just couldn’t step his game up far enough.
