The answer so far is no. He is not capable of being a head coach.
My prediction is that Snyder, Keuck, and Dunlap will return next year. While Morris has been much improved, all expectations are that Garner is this terrific QB and therefore has QB skills far greater than Morris. With the TE's and better WR's, I think Snyder sticks with his main coaching staff for one more year.
If next year is just like this year then Snyder and all will be gone. I don't think Kopp can wait any longer.
Kopp could make a move at the end of this season. So far, he has not provided a public vote of confidence to Snyder.
What will be interesting is to see if the assitant coaches try to jump ship at the end of the season. If so, that tells me that Snyder will be gone at the end of 2008 if he doesn't win. Assistant coaches have to look out for themselves. They know when the ship is ready to sink and they will want to find new jobs before they are all fired.
Time will tell. Maybe the season will be salvaged and things end on an upswing. I hope so.
