Marc Sessler has a great list of his all-time favorite broadcast duos. Some new and some old make the list, but 3 of my favorites on his list are Pat Summerall/John Madden, Kevin Harlan, and Joe Buck/Troy Aikman. Jack Buck also holds a special place in my heart, but for calling baseball games.
The Seahawks and Ravens have discussed signing Antonio Brown. AB in either of those offenses would be legitimately scary if he could actually stay on the field. I do hope that he got some help while he was out of football this past year.
