With a guy like Mettenberger (who I do love), you could justify it as a long term move given the length of his contract. If he comes in after the bye and shines, you can move forward with him for the foreseeable future. If not, his price tag wouldn't prohibit you from drafting another one in April. From this standpoint, I'm certainly happy for them to try it. Just can't see them admitting after a couple of months that they picked up the wrong options.
