1. No because I'm not convinced that Willis is really much better than the others. He certainly has some nice abilities, but I don't know that it will translate any better than the other options.
2. It depends on what they give up. Again, I'm not convinced he's a sure thing, but I guess if the Lions are, then do it. Heck, if they're really convinced that Willis is the guy trade the Rams pick next year for someone's second round this year.
