For the most part, NFL GMs must look through the windshield rather than the rear-view mirror, so to speak. Count me in with those who regret Cobb having departed. This season he would have been the team's best slot receiver other than Adams (when he plays there) had he remained with the team and stayed healthy.
In spite of that, I agree with those who feel that the time to depart with Cobb was upon the front office. His short and long-term cap numbers, his injury history, and his beginning-to-fade explosiveness all intersected at just enough below the "Gotta Keep This Guy Line" to force the sad decision. Un-sentimental, I agree, but probably the most logical one that had to be made under the circumstances.
Then again, for the right price, you never know about 2020. Tramon may have laid the groundwork for that consideration. I just won't hold my breath though.
