I'd hire a young unknown coach before hiring Gruden. Gruden is at best only going to get you mediocrity which is the reason we fired DA. If you can't get one of the top guys just take a chance on a young unknowns like Brady, Moore, or Kafka. They will either flame out which will give you the picks to rebuild and get a QB high or they exceed expectations and turn out great. There just isn't any reason to tread water for 3 years with Gruden when you can take a lottery ticket on a young unproven coach.
And if that young unproven coach is a disaster, Loomis goes and we rebuild the team from the ground up. Gruden is only going to at best prolong the 7 to 9 win seasons and will have some worse seasons depending on injuries. Gruden just isn't the answer to anything.
