Lots of excuses for Dunbar not playing well and some of them were mentioned here. I'm totally unsurprised that he received no interest. There was nothing about his game last year that I liked. Bottom 20% in the league performance wise IMO.
I'm pretty high on drafting a replacement somewhere around the 4th round. Or earlier if we get extra high picks and the value is there.
He has a good attitude but it's too bad his skills don't match it.
