Osi is obviously an upgrade to Ball but I'm not sure he is going to be worth the price. I'd rather have Mario as well. If we look FA on the OL it should be at C. We can find quality OGs in the draft and upgrading C probably improves the OL more than an OG right now. However, we could actually draft Konz and still sign a vet C and have Konz play RG for a few years. Either way there are a number of guys we could draft to play RG but after Konz I'm not as excited about the Cs available.
