A.J. Cann is the best pure OG in this class. He's a mauling run blocker that would be a huge addition to any PBS team. Pass pro needs some polishing but he's not far off there either.
However, when you count the LT prospects, I'd say(considering our scheme and preferences):
1. Brandon Scherff
2. T.J. Clemmings
3. A.J. Cann
4. La'el Collins
5. Ty Sambrailo(one hell of a mean steak on this kid)
Haven't seen enough of Drango, Le'Raven Clark, Vadal Alexander, Ronnie Stanley, or Ereck Flowers yet to rank them. I like Ogbuehi but I don't think he's big enough for us at OG.
Keep in mind that's ranking them as an OG. Collins will go before Cann because Cann is a pure OG whereas Collins has the versatility to play OT and OG.
