If Armstead retires, it will force Grier and Co. to eat the money, and draft someone. The only question is will they be able to select a quality LT. Oh and I will reiterate the iteration for those who have a certain opinion, "at least we will have him for 11 games", which 11 will he miss? Two Buffalo and two Jets, or half of our AFC games, or will he miss the last 5 plus a playoff game? "Rest him" will make no difference, from our human perspective, limited data and processing ability, injuries in the NFL are chaotic and cannot be avoided or predicted real time. Other than bigger helmets, knee braces etc. it's gonna happen, with some more than others.
