Per the chronic - White will start, and they will rotate Caldwell in every other serious.

“They both worked extremely hard, and they're going to split time right down the middle unless one of them is just playing his tail off,” coach Gary Kubiak said after Friday's practice. “It's a great opportunity for both of them."
I gotta tell you, I don't like this one bit. How are they going to get any continuity if they are swapping every series. If Caldwell isn't ready...don't play him. Subbing guys every other series makes about as much sense as subbing them every third series...what a minute.....we did that too

Hopefully, one of them will stand out, and we can set up the Oline for the balance of the year. I am hoping for Caldwell. White is a nice backup, but Caldwell has got to produce for us in the future.
