At least Graham has an unusual skillset that you could justify taking him that high, kinda, although there are other d-linemen with similar skillsets available down the board.
To me, it's Hunter or trade down, because even Graham isn't really a top 5 pick in my mind. If you trade out and still keep a pick in the top 15, you can get a Banks (my favorite LT prospect), Campbell, Conerly, Membou, Simmons, whoever, and still have gotten enough value with the additional draft capital. Maybe you can steal a Matthew Golden at 36 in that case, with another 2nd rounder to back up that pick.
