5 first-round prospects 49ers can now target in NFL Draft after free agency

Graham Barton represents an interesting quandary for teams given he's a prospect who could legitimately start at all five positions on the offensive line, providing some flexibility that's almost unmatched in the NFL.

Niner Noise's John Porter specifically highlights Barton as an interior blocker, and certainly, that makes sense, given Barton has short arms and some teams are a bit hesitant to trust such players on the outside of the offensive line.

But I'm not sure I share the outlook he's restricted to being a center or a guard. He's an excellent blocker given his power, blocking prowess, athleticism, intensity and ability to fit into multiple schemes. This includes the 49ers and their zone-based scheme.

Left tackle might be a step too far with his arm measurements, but good technique can overcome this limitation so it isn't impossible.

At the very least, he could project as a good right tackle.

And it should also be noted that the 49ers place a lot of stock into positional versatility. A player who can adequately cover three, four or even all five spots on the line would be an excellent selection at No. 31.
