Personally, I think it's been a success:

* The offense will be better with two talented TEs
* Lang will be missed, but not at $9 MM per
* The Packers only lost two notable FAs (1 count for Lang, 1 combined count for Lacy, Jones, and Tretter)
* The defense will be better as I firmly believe last year was significantly below average performance for Rollins and Randall and they'll improve simply by regression to the mean.

Downsides are that the Packers need a RB. And could use another talented CB and pass rusher. But they aren't far, and I think it's absolutely ridiculous to call them one of the worst performers during the first week of FA. I think with two TEs, the Packers O will be even more difficult to stop than the end of last year (barring injuries).

I'm not a koolaid drinker (most of the time), but I'm more optimistic than it seems many others are.
