Lucas Patrick was brought in last year to replace him, but ended up playing in other positions, and getting hurt.
I might not be the "sky is falling" kind of guy, but I too have been underwhelmed at the FA approach to fixing the O-line.
The one position that I thought might be a place to fix through FA was Center, and it appears that they are going into the season with Whitehair, Patrick or a rookie slotted at Center. Patrick is likely the best of three bad options. The Center has a lot on his plate, calling out protections, making sure the exchange with the QB is perfect, and handling the big boys up the middle/ getting to the next level in space. That is a lot for a rookie.
I think Center is more critical than RT, because I think Jenkins can play RT, with him and Davis we just might have a road grinding right side we can run behind. I think Jones showed a lot for a rookie, and hope he can improve. Whitehair is better at guard, and maybe we can draft a guard to press him/replace him.
I think McGovern is still available, but I guess at 30 years old, there is no chance Poles goes out to get him.....
Hell with it.....bring Mustie back, he might actually be the best option
