Jumping in late here.
I am unhappy in how Buck had been using Streveler. He allowed our 2nd string QB to be used as a battering ram on almost every play - the defences knew this and keyed on the run. Buck wasted Streveler's talent, and he was broken down, game after game. He did not let Streveler attempt to play as an actual 2 dimensional QB. If he let Streveler in for a series once a game - and let him run the O - at least the team, and the fans could have seen what Streveler was capable of.
This is 100% on Buck, and yes, our O has had bad-luck when it comes to injuries, but he needs to do better.
