Starting Left Guard: Jamarco Jones
Assuming Mike Iupati does not return, which seems unlikely, the Seahawks will have a wide open competition for the starting left guard job this summer.
Jamarco Jones, who was originally drafted as a tackle, seems like the early front runner for the position, based on his strong work as a replacement at both left and right guard last season.
Jones will face competition from returners Phil Haynes and Ethan Pocic, who both played some guard last year, as well as newcomers B.J. Finney and Chance Warmack.
Finney and Pocic can both play center, which may make them more likely to begin the season as versatile bench pieces, but Haynes and Warmack will no doubt push Jones for the job.
The team also has Jordan Roos, Demetrius Knox and Kyle Fuller on hand as depth options, and they are reportedly interested in bringing back free agent Jordan Simmons as training camp competition as well.
Left guard will be one of the more interesting battles to watch in training camp this summer.
