I'm not sure why we make weekly posts about Otah, Carolina is in a perfect situation with the dude. If he doesn't perform, we are done with him at the end of the season. If he performs outstanding, we trade him because you never dude who only performs well in his contract year, and get some value for him in a trade or let another team buy him outright. And for whatever reason you don't believe that Bell can't improve, which I guess means that Cam can't improve either.
Do you understand the concept of Free Agency. As chef17 stated, if we don't re-sign him HE WALKS. There will be no trading of Otah, unless we sign him to a big contract and then trade him....which is highly, highly unlikely.
