As well as Bulaga played last season there is a significant risk involved in extending him. Jason Spriggs was supposed to be the guy and my guess is Gutey gives it another shot.
I've heard more then once now supposedly the Packers consider Jenkins as a potential long term solution at RT. Bill Micheals just brought that up again last week and claims GB is considering it. He played both RT and LT at Mississippi.
I love him inside and the job he did his rookie year. I just don't know how he'd be kicked out to tackle.
As for Bulaga, yes of course I'd love to see him back but the injury history cannot be ignored. In 10 years, he's had 2 seasons where he started 16 games. "Better off moving on a year early" saying keeps poppin' in my head when it comes to players like this with injury histories. See TJ Lang, Josh Sitton, etc.
