Well, this is old news that came up a month or two ago. I think Ainge has big interest in bringing KG back at this point, especially given what he's taught the young guys about defense.
At his age, years can't be a big factor, so the C's should be able to keep him as long as they are willing to match salary.
And I have zero problem with Danny giving him 2 years. This let's KG and PP (and maybe Ray) all go out together in 2014. We get two more years to teach the young guys and then in 2014 either make a run at some free agents or look to repeat what Danny did in the summer of 2007.
