I agree. Zack Martin is being overrated. Sua'Filo is probably as good at OG. Yankee is good also, but might best in a man blocking scheme. I think Marcus Martin can start at Guard or Center day 1 in the NFL. There are 3 college LTs that appear to have very high upsides at Guard but might need a little time to be ready.
At OT, Morgan Moses has way more upside than Zack Martin, IMO.
Having OT/OG flexibility is not overly helpful on game day. OG/OC flexibility is much more valuable. They're always going to bring at least 7 OL to the game with 1 OT backup and 1 interior backup.
Broaddus is pimping Zack Martin, but he also loved Floyd last year. I encourage people to watch the game footage of these players themselves and not just go by what Broaddus is telling you. He loved Floyd last year. Broaddus seems like a nice guy, but he would like to be a scout again but can't get a job doing it. Maybe there is a reason for that.
