I'm just throwing this out there. I don't know that this season with all the off-the-field hoopla surrounding Kaepernick is the best gauge of the type of QB coach Day is. It certainly was not a typical season in that regard. Just have to trust Urban.
Also, to this same point, I remember when Marshall announced that Bobby Pruett, defensive coordinator for the Florida Gators, would take over as head coach for the Herd following Florida's national championship game against Nebraska in January '96. As a life-long Buckeye fan that attended Marshall, I watched that game to see what Marshall was getting. If you remember, Nebraska absolutely waxed the Gators that night (these were the Lawrence Phillips-vintage Huskers), and I was left with an uneasy feeling about it all. Coach Pruett ended up being the winningest coach in Marshall history (no jokes, please - I know that it pales to Woody in Columbus, but it is what it is), so I learned that a snapshot doesn't always tell the whole story like with Kaepernick in SF this year. Urban has my trust on this.
