I don't see a lot of angst over the INTs, . . though 4 in three games is worth noting. (He threw zero INTs in his first 85 attempts, then threw 4 in his next 85 attempts). INTs could hurt against better teams. Mostly I think the board is thrilled with Book and the way he's played. Mostly I see descriptions like "winner" and "leader." He's played extremely well overall and the majority on the board are crediting him with it.
