Edwards is one big and physical blocker but he's also a former TE who can move well for a huge dude and Kromer loves to move the OT types inside. They didn't draft him to play RT because they have a top ten RT in place. His immediate role is OT depth but if he can show well on the interior they may let him put some pressure on Blythe.

Guy like him isn't going to get pushed back into Goff's lap. He's not as quick as Blythe but the power would be a big upgrade.

There's another option too of course but I think Evans' feet on the outside are better than those of Edwards so I suspect he will settle in as depth at OT.
