They were counting on Cade McNamara to provide leadership on the field, and to manage the games with a veteran mind.
Once he was lost for the year with that injury, they've relied on Deacon Hill (who looks lost in the woods out there), whose accuracy is flat-out bad...
When you combine this with the ineptitude of Brian Ferentz as the OC, that pretty much sums up their season, where they were lucky to win 10 against all of the lightweights.
