I'm feeling that both guard positions are set, as long as Amini holds up this year. If Bell proves the doubters wrong this season, bring in a young tackle to take over for chandler for a year. groom him to be the LT long term. Chandler would be good depth. I think Chandler is more of a LT than a RT, anyway.
Something to keep in mind. Kalil isn't getting any younger, and his cap number is getting up there. I don't see a move being made anytime soon, honestly; although, stranger things have happened. He's still elite for sure. If there's a tempting center sitting in the 2nd round next draft, I wouldn't be surprised if DG bites. Especially if Amini doesn't last the year. Insert him at LG until Kalil's play drops.
