This is quite simple

Center doesn't matter because Shelton is marginal at best. They can fill Center via rounds 3-5 provided they don't screw up the OGs. And we have Avila as a stud in year two on the left.

So. If they retain Dotson OR bring in a LT and move Jackson to RG they'll be good. Just make sure those two guard spots are strong so 9 has room to step up in the pocket. By doing that you also take heat off those tackles.
