You answered your own question by listing all the general options, zn. It will be one of those listed options.
Now, if you’re asking for my personal best swag?
Corbett will be extended either as an OC or an OG depending where he plays this year.
Assuming Corbett stays at RG, then one of Allen, Shelton, or Anchrum will be our starter at OC in both ‘21 and ‘22.
If Corbett does in fact move to OC then our ‘21-‘22 RG will be one of Anchrum, Brewer, or Evans.
I lean toward Boom being extended for starting LOT in ‘22 at some non-budget busting price.
But I could easily see our future LOT coming from trade, FA, or draft if Boom’s run blocking were still substandard. Rams will simply have to find the money and I have no doubt that they will.
