After reading all these comments, I'd just like to add the following: This team was 5-11 last year. Yes, there were injuries - lots of them - and it showed that our backups were not up to par. Now, I look at the roster as it is after the cuts, and I see no position where the team does not have multiple options (in many cases, better options).
Forsett is an example. Yes he got cut, but 1) each of the other RBs has shown the necessary capabilities (run, catch passes, pick up blockers, etc.) and 2) RB is an example of a position in which an inexperienced, but naturally talented youngster can succeed early on in the NFL.
That having been said, I will assume that the coaching staff has picked the best 53 out of the original 90 while the FO will be watching the other teams' cuts to fill any holes.
I remember that a 5-11 record meant that they had to make drastic changes (not just superficial ones) - and watching the four games, reading the articles, etc., it looks like they did what they wanted to do: the team got younger, faster and more physical.
