I'm with the posters here who believe Hundley was too expensive (two draft picks I believe) to move up for. Usually TT does the reverse. The only thing that makes sense, at least to me, is that this is a vote of "no confidence" for Tolzien.
And then Blanchard comes along and plays surprisingly well. But will TC and pre-season play be enough for the Packers to cut Hundley and go with Rodgers, Tolzien, and Blanchard? That seems very unlikely absent a trade. What seems likely, if Blanchard continues to play well, is that they hope Blanchard clears waivers and stash him on the PS. Seems Blanchard has a better chance of clearing waivers than Hundley. And in any case, I don't see TT cutting a guy he traded up for?
I think TT is not convinced Tolzien is the guy to backup Rodgers. Thankfully, as Captain points out, Rodgers has been very durable since staring. But backup QB is critical to this team as we saw two years ago. I think in the next year or two the backup will be Hundley or Blanchard, not Tolzien. I'm sure that will draw some forum fire, but it's just me speculating.
