That's a tough one. I understand the other posts, but I'm not sold on Thomas. If possible, i'd wait and see how the Thomas/Bell situation plays out. You can't deny that Bell played very well, even if i was against DET. LJ on other hand played poorly, but against a top notch defense. My advice would be to stick with what you have for the moment.
