2016 Cap numbers:
Sitton = $6.6 million
Lang = $6.2 million
Tretter = $788,850
Lane Taylor = RFA (last year's RFA 2nd round tender was about $2.4 million)
So, I have to ask why are the Packers going to spend almost $13 million on Sitton & Lang? Why not just pay Tretter and Taylor a combined $3.5 million and use the excess $9.5 million elsewhere (like ILB or TE)?
IMO, Tretter would be an upgrade, mainly because Sitton has had so many nagging injuries and chronic back problems. We saw first hand how much more athletic Tretter is when he played LT the week after Sitton got destroyed playing LT. Not saying Sitton is a bum, he's a fine guard, MM should never have stuck him at LT. But, Tretter is an ascending player, and Sitton is entering his twilight.
Lang is also a fine guard, but, is he that much better than Tretter or Taylor in 2016?
They gave up 49 sacks in 2015. Wasn't really Sitton and Lang's fault, I'd probably blame the injuries to Bakhtiari and Bulaga for most of the sacks. But still, they're allocating $13 million on what are supposed to be a couple of stud OG's, and the line ain't getting it done anyway...what's the point?
Also, in 2014 and 2015, the Packers struggled mightily to convert 3rd & 4th down with a yard or less to go. Again and again the RB's got stuffed in those situations. If Sitton and Lang are so darn good, why is that?
I'd be fine with a 2016 offensive line like this:
LT Bakhtiari
LG Tretter
C Linsley
RG Taylor or Walker or Rotheram
RT Bulaga
(I could be talked into keeping Lang, and playing Tretter at RG.)
