Aaron does deserve the ink! I am a Green Bay-area resident and have seen Aaron play amazing on field, but I have the greatest respect for his off-field conduct, the way he handled the Brett Favre situation (trust me, he was the only grown up in the entire issue here in Wisconsin), and fighting through all kinds of adversity (shoulder, foot, hamstring, Favre) to show his strong character.
No. 12 is truly more respected in my book than no. 4!
