I'm not going to pretend that I am a guru on contracts and guaranteed dollars and such, but with some of the contracts being thrown out the past few days, 13 million of 30+ million doesn't seem like an astronomical amount of money to me. From what I understand, all of the obligations to the Packers regarding Graham can be eradicated after this season if he flops.
He has top-5 TE talent especially with Rodgers throwing the rock. For the Packers to have snagged two guys basically at the expense of Jordy who could prove to be big time contributors, the Packers have done quite well.
Again, aggressive, but not careless. The biggest point for me was that neither of these signings will cause the Packers any long term cap issues. BGK is impressing me thus far.
