I would trade every member of the Dallas Cowboys(Owner, front office, coaching staff, and players) straight up for Howie Roseman. Roseman with an expansion roster would win a Super Bowl before the current Cowboys. Roseman has only been in full control of the Eagles for 2 years. Before that Andy Reid then Chip Kelly had the real power in making personnel decisions.
Roseman is genius working trades and salary cap. Never was a good talent evaluator. I (and a lot of people who follow the Eagles) give more credit to Joe Douglas for talent evaluation.
While Roseman was in exodus from the Eagles he consulted with successful GMs and other FO personnel from around the NFL, and all the other sports learning how to build a successful roster. Looked in the mirror and grew personally as he realized he rubbed people the wrong way.
The roster rebuild was done out of necessity after Kelly ran off most of the corps of the team and brought in pieces that didn't fit. It wound up putting us up against the cap bringing in new players via FA and moving on from players after the first year of their contracts. We had to eat a lot of real money and dead money to unload the Murray and Maxwell contracts.
It seems we're in a position now to draft a year or 2 ahead to have players ready to take over from the vets 2 and 3 years down the line.
