Re-sign Fant, start him at Right Tackle, and promise him Left Tackle once Duane is done. I feel pretty strongly that D Brown will retire after 2020. He's had some injuries, albeit minor ones, lately. He's getting up there, but, he's still playing at a high level. So I think 2020 will be a great year for him, but I'm predicting that some team success, and minor injuries will cause him to consider his future next year.
Keep Joey Hunt, an economical, functional backup for Guard and Center.
Extend Justin Britt, bring his 2020 and future hits down some with a signing bonus. I don't want to go through another new Center when the rest of the line could be in flux.
Keep Ethan Pocic who is currently on IR
Keep Fluker. He played well, and was available most of the time.
Jamarco Jones, Left Guard. He can also fill in at Left Tackle in an emergency
Phil Haynes at Guard
Creature Man, Jordan Roos at guard
Draft/Sign a Left Tackle Prospect and Guard.
Don't forget Tight Ends in this equation.
Re-up Luke Willson! That guy is INVALUABLE as a blocker, pass catcher, and all around team mate!
Jacob Hollister, what a STEAL this guy was!
Will Dissly, no brainer. LOVE this man.
Swoopes on the Practice Squad
Draft/Sign a "young" Tight End, or an Offensive Lineman/Tight End Hybrid like George Fant or Gary Gilliam...OR Jason Peters.
Cut/Drop: Iupati, and Ed Dickson. Dickson is a great guy, great talent, but he's 32 years old and has a horrible injury history the past 3 years!
Considerations:
Jordan Simmons on IR. Has injury history, but deserves a look this year.
