There are probably several threads similar to this one, but like most of you I am extremely frustrated with the way things have been since 2003.
These are just my opinions with a small explanation of why I think they would work.
Move 1. Trade McFadden for more pics.
Bottom line is he has a ton of talent, but not the health to go with it and I think it's safe to say the ZBS hasn't worked for him and even if it would, he hasn't been on the field enough to gain the experience he needs to be successful in it. The Raiders need good players at a lot of positions, not 1 great player at 1 position surrounded by a bunch of nominal players. More draft pics will fix this issue and McFadden is the only player with any trade value.
Move 2. Trade McLaine
With the attitude issues and off the field problems there won't be much of a market for him but he's not worthless, someone will give up some pics for him.
Move 3. Hire Gruden
The last coach worth a damn that ever coached this team and the only one to have success under Al Davis's rule which is in itself no small feat. I'd rather have an offense that pics up 5 to 7 yards every play with short passes and scores then watch a constant string of 3 and outs.
Move 4. Sign Alex Smith
Putting him together with a west coast offense minded coach like Gruden is a match made in heaven. Smith doesn't throw the deep ball, but he's mobile and smart and he can make all the throws in the 20 yard window. The receivers on the roster now are guys designed to stretch the field, Carson is a pocket QB who can make those throws, but the line can't protect him long enough to allow him to make that type of offense successful. They can however protect for a few seconds in order for Smith to get the ball away in that short window and if they can't then Smith has the mobility to buy more time to make a throw on the run or scramble for positive yards, plus I'm sure he'd love to be a constant reminder to the 49'ers by staying in the area.
