Arthur Blank apparently doesn't have (or want) control of his organization. The management team of a Franchise that has never won a Superbowl was no doubt threatened by Belichick. Blank, who is a very smart and highly successful guy, didn't have either the ability or the interest to challenge them. Some Franchises are doomed from the top...most notably the Jests. The Falcons seem to belong, at this point, among that group.
The Falcons' press release states that Morris will "report directly to Arthur M. Blank...on all football matters. Rich McKay...continues to represent the team on league matters and the NFL's Competition Committee. Greg Beadles...will continue overseeing all...business operations." Pretty much says it all. Blank is 81 and totally dependent on the hired help. Robert and Jonathan Kraft are hands-on in all of those areas. Same for the Rooney's, Mara & Tisch, Glazer and Lurie, along with a few others.
FWIW, I think that "3--28" and his premature trip to the Sidelines took the NFL life out of Blank (the game did the same to Matt Ryan....the look in his eyes for the last Quarter and OT said it all...). The bureaucrats who run the team are still around and apparently will be for a long time.
