You're completely dodging the big picture here.
Between 2010-2011 Eagles made him an offer. The Packers either matched it or exceeded it, I can't recall exactly. Fact of the matter is, he could have been with the Packers for the same money he got in 2011. Jenkins chose the Eagles.
Now he's cut by the Eagles, the team he chose over the Packers and he's being interviewed by a Packers writer. Let that sink in for a moment.
Jenkins knows full well who has got the blame for his being an Eagle and not a Packer.
Of course he's going to say he would have signed with GB for less money (appealing to those who feel players are overpaid) and continue to let the blame fall on Thompson, instead of admitting he chose the Eagles over the Packers, thus, alienating him with a portion of the fan base that he might end up playing for again? Think about this.
Bottom line, he is now a Giant and and he chose to leave the Packers. Accept it and move on.
Regarding the Packers signing ~30 year old free agents.
Thompson believes, and this is from Ron Wolf too, that you have to groom offensive players, but you can add free agent players in defense.
Offense = draft and develop
Defense = draft and develop and fill in spots with free agents
Not overpaying for a near 30 year old RB ... not much of a surprise, lol.
