pre-draft OL depth chart?

LT- Whitworth, Murphy
LG- Saffold, Brown
C- Sullivan, Rhaney
RG- Havenstein, Jackson, Wichmann, Donnal, Arkin
RT- Robinson, Williams

That is quite a log jam at guard.... Someone has to go. I'm highlighting the ones I think are going to stick for sure. Others TBD. Could the Rams add an OT in this draft?... A Will Holden from Vanderbilt?

I'm not a fan of Donnal but I know he can also play some tackle and versatility always helps an OL stick around. Brown and Wichmann are going to need to be able to play center at least in emergency capacity.
