This article speculates the promotion of Roseman to GM may signal a reduction in Reid's overall power in personnel decisions. This is the second such article I've seen on this, btw. And it does fall in line with Banner's previous reminder of the definition of insanity. From the article:
The weight on the seesaw - and we'll leave alone the observation of what it takes to offset Reid's side - was redistributed when general manager Tom Heckert Jr. decamped for Cleveland and was replaced by Howie Roseman, a Joe Banner protege who began his career here as a salary cap wonk.

In Philadelphia, Reid has held all the real power, but as the seasons without championships pile one upon the other, there is room for other voices in the front office to be heard. With an alignment of team president Banner and Roseman, the critical mass needed to influence decisions has probably been reached.

Picking apart the differences between the Eagles and the Cowboys, for instance, Banner noted that Dallas might have done a better job putting together its roster, which gets back to the whole player-personnel business. If the president wasn't satisfied with how that side of the operation worked, from draft day to free agent scouting to formulating trades, then it's no surprise the Eagles have a new general manager.

One thing is certain, however. When the franchise powers assemble at that meeting table, Reid can look around and know he doesn't have as many votes in his pocket as he once did.
