From what I hear in Dallas Irving is expected to get a 2nd round tender. Odd that the author didn't mention this in his article. Cowboys aren't going to sign him long term...this year. So if the Cowboys don't match a Bears offer he could be had for the 39th pick in the draft. He's a young tall pass rushing DT but I do agree with the article that he could project to a 3-4 DE.
He would start for the Bears, no question.
But do you give up the 39th pick for a position that's OK depth-wise when you have so many pressing needs at other positions?
