I would prefer this as well. But I'm not an offensive line coach. I have to remind myself that these offensive line kids are not conditioned for the long nfl season. Very few are able to handle that kind of worked load much less learn all the protections. Sometimes they are forced to start out if necessity for bad teams, maybe we are ine of them, but it's not the preferred route for coaches.
Christensen may be able to start soon but the big boy Brown may take some time on the conditioning side to be able to start.
