In my opinion, it depends upon what happens on the field. He could adress the lines (ala Mike Williams) and do it with the wrong players. By the same token, he may not address any of these positions because he and the coaches may realize something about our current players that we don't yet see. Either way, what's most important is wins and losses and how the team looks on the field.
Marv, for me at least, gets a few years to put a winning team on the field that is consistently in the playoffs. After 1 year, I'm encouraged. But, I'm certainly prepared to say Marv was a great coach but totally blows as a GM, if it comes to that.
