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.
If Smith hits FA then I am fine with him being the priority. Not sure that happens though. Tend to think it won't happen in fact. When was the last elite OT to hit the market not named Whit. Because teams overlooked him due to his age. Cornerstone types who are elite rarely hit the market.
Granted he is 33 which means this is probably his last contract. But still I would guess if anything it will be a tag 'n trade circus with him. I'd love to see it happen. LT confidence strongly affects Stafford's gunslinger tendencies I think. But there is something to be said for a philosophy of building a line with strong interior so the QB can step up. Because then you can succeed with a lesser talent at LT who you would not need to pay elite LT money.
Also and btw if they are saying in their draft strategy "if Penix is there we're going to take him" that might affect their plans with the tackles because his blindside is on the right. From there ensuring the interior is sound means he would have that pocket to step up in on most snaps and lessens the load on Havenstein if and when the kid has to play.
So I'm not a "sign Dotson at all costs" type. Rather an appreciator of what Dotson brings to this line and I would feel a lot better about it if they get him inked at a reasonable deal prior to the market. Don't think that's gonna happen but I do think he is a guy who is capable of giving you years of elite play on the interior if his head is right.
