Some Thoughts:

• I really like what Joe Burrow brought to the table yesterday.
• We have talent on the OL. It's a question of finding the right combination and cohesiveness.
• Marcus Baugh will have a really nice year.
• Gibson starts IMO. He's going to be fantastic.
• You have to like the depth on the DL. Hamilton and Cornell really stood out yesterday.
• The LB Corps will be solid at worst. 
• I think we have solid depth at CB, not so much at S behind Hooker and Burrows.
• Nuernberger makes a leap. He's got the leg, he just needs more consistency.
