I think they have other options at RG if the price gets too high for Dotson. I am in the camp of allocating top OL money into tackles especially Left tackles. I think a better option than paying/overpaying for Dotson, is to take that money (15-20 mil) and to sign Tyron Smith at LT. If they sign Smith they still tender Jackson and move him to right guard while also keeping Noteboom. As far as cap space is concerned Notboom essentially cost 5 mil in cap hit to keep him (15 mil dead cap to cut him) for a backup that is starter capable. He provides excellent depth as he can play 4 postions on the line in case of injury. (Smith could be the next Whitworth). Also if they let Dotson walk the Rams will get 3rd or 4th round comp pick as well. This all hinges on if Dallas can resign Smith or is willing to resign him.
