With Strief possibly getting the starting nod at RT, he will be less likely to be the "swing" tackle in those certain situations. Could Charles Brown take that spot in his absence?

Brown did play tight end in high school and was a 4-star recruit for the position. He put on some weight and ended up converting to a tackle and has been ever since. I'm thinking he still has some pretty good skills at the position even though he's about 4 years removed from it, so maybe he could excel even further than Strief did (receiving-wise), while also save a roster spot in place of another TE.
