You addressed how dangerous LSU's offense is in an above answer. I also think Clemson has the skill positions to be dangerous in a similar way. Being a predominantly zone team, do you think OSU will have to switch to mostly man coverage to deal with such precise QBs and WRs?
People swear man is the better choice. I don't think it is. You have to play a mix, but switching to man makes too hard on your corners and SAFs. It's also harder for your rushers to be aggressive because it creates rush lanes and the backers don't have vision to cover them up. The reality is, also, that Joe Burrow makes some great passes. Trevor Lawrence makes some passes. But these guys will make mistakes throwing into zones. Last thing you want to do is have their coordinators scheme up man-beaters that have players running wide ass open and make it easy of them that way. I don't think man coverage is better than zone and I don't think some is better than man. My championship team was a base cover 4 team and we made it work. USC used to play 3 deep. Other teams play man. It's a preference.
