It's unlikely to happen, but I think LeCharles Bentley is right when he says that the 49ers would have more success moving Anthony Davis from tackle to guard than they would moving Alex Boone from tackle to guard. Bentley, who works with Boone in the offseason, said as much to CSN Bay Area in a story about how Boone could compete at right guard during the offseason. Davis is tall at 6-5, but Boone is three inches taller. Furthermore, he's long-legged and has a narrow base. When he was coming out in the 2009 draft, there were questions about whether he was too top heavy to play tackle, which, along with his well-documented off-field issues, caused him to go undrafted.
