With Whitworth I don't think they "get rid of him", I think he simply retires after 2018 (he will be 37). I think that's his plan.
Saffold will be 31 heading into 2019. I'm not sure you give him another contract heading into his 10th NFL season. Havenstein and Brown? Probably one stays?
In any case I would draft two OL each in 2018 and 2019. Not saying any have to be 1st round picks but they also can't all be day 3 picks either.
