You are comparing Pace to Emery? Emery was all talk. Pace is not afraid to make moves, which is something we are not used to. I don't see any major issues with these moves.
So if the Packers cut Sitton before we cut Slauson, and we signed Sitton and subsequently cut Slauson, would anyone care? They would all say it was a great move to upgrade the O-Line. So as of today, we are in that exact situation.
For the Kickers, Gould was shaky the last two years and missed some during the preseason. The team had their eye on potential low cost replacements who could perform at or above his level and they made the switch. If we are complaining about Kickers, they I think our team is in pretty good shape.
For the Long Snapper, from what I have read, it comes down to the Kicker preference, so Robbie may have wanted one guy and then once he was released, the Bears went back to who Barth may have been more comfortable with. Again, if we are talking about LS's, then we are in good shape.
