It’s more of a *somewhat* educated guess at this point. I think Kline just seems like the most-likely starter if Wendell were to get cut and Connolly takes the starting center spot.
As for Devey, I think last game they just wanted to get a true sense of what he’s capable of… how many positions can he really back-up and if he had to go in as a guard, could he hold up.
He’s 6’7”and really more suited to being a tackle, similar to Marcus Cannon, but how else can you find out just how good a player is at a different position if you only ever see him there in practice. Hence, they threw him into the fire in week two and tried him all over the line.
This week I think we’ll see a starting line with Kline at right guard unless Wendell’s in there and Connolly slides back to where he spent the last two years.
