I'm a bit confused. Are both of you advocating for not discussing it?
I think most everything is up for discussion in the off season. Sure none of us "know", but on a message board, I think it is fun to have opinions.
Kirkpatrick's best years are behind him now, and his availability and productivity have dropped way off over the last couple of years. Bringing him in for "competition" just takes away a camp roster spot for someone who may be a better bet in the long run.
I've had my eye on Throckmorton for a long time. He had a terrible senior bowl, but he's long on experience, and has played at multiple positions. At the very least, he would satisfactorily make up for the loss of Haeg.
