I see what you're saying and this has been thought about and the reasons why Green Bay wouldn't do it are this.
Matt Flynn would make top 5 QB money like $14.5 Million. That's almost twice what Aaron Rodgers is making.
Now of course they can't let this guy make more than Aaron and even though Aaron signed a contract just a few seasons ago
guess what his Agent will say .... SHOW ME THE MONEY. And he'll say it as soon as Matt signs the tender.
Also if no team is willing to give up what Green Bay wants, now they are stuck paying a guy who sees the field once or twice a year because the money is guaranteed. And at the end of the season your choices are to franchise him again or let him go. Franchising anybody for trade bate is risky business,
especially if they are unproven.
The Eagles still had Kolb under contract which was a big advantage. The Eagles practically stole Cromartie and a pick from
Arizona for a guy who got outplayed by Some dude named Skelton.
If you were going to franchise to trade someone, they would have to be a Patrick Willis, Drew Brees or some high calibre player. Goldson is good, but
Franchise him. Of course you do, but only to work out a long term deal imo.
