These fans of which you speak clearly must ignore reality to indulge their silly frustrations.
Here's reality: Ted has spent EVERY god damn Cap dollar he's had and that is over 1.5 BILLION dollars. The only amount he has not spent of this 1.5 BILLION is the 7.9M he just rolled over. And that was kept for a mid season acquisition and/or to extend Perry, Elliot, Jones, Hyde and/or Tretter, if they performed as expected and the other side agreed.
A fan that ignores the Cap insisting Ted should spend over the Cap has got to be a nut.
More reality: The team Ted inherited from Sherman did not have quality players worth retaining; so Ted used the money not used to extend and sign his own players and filled the holes by signing outside FAs.
Even more reality: Generally, after signing his own players, if there was money left he signed outside FAs.
The opinion that Ted should just sign more outside guys is patently irrational and it makes people more stupid after hearing it. Now the Argument Ted should have signed X instead of Cobb, or Y instead of Daniels or Z instead of Bulaga is an opinion that is worth sharing.
