"IMO, it is far too soon to judge how a team manages the 2006 cap when there are 6 months left before the regular season starts"
I think that it remains true in 2007.
That being said, I personally would not focus on whom the Colts lost but who remains on the Colts. After all, each team in the NFL is going to experience a roster turnover of about 10 players. Some players have to leave a team in order for a team to have room for its rookies.
If I were a Colts fan, I would be encouraged by this forum's take on the 2007 Colts. After all, this forum in March 2006 was pretty much wrong on the 2006 Colts.
