Howie Roseman knows he has to try everything.

Sports Illustrated's Albert Beer reports that the Philadelphia Eagles' general manager took a swing at trading for All-Pro running back Christian McCaffrey before the Carolina Panthers sent him to the San Francisco 49ers on Thursday.

This is what the report had to say:

Last Monday, GM Scott Fitterer pulled McCaffrey aside to give him the landscape, tell him that he planned to listen to offers and also that he’d be comfortable hanging on to him. … More calls poured in Tuesday, with some teams just fishing—offering a third-rounder or a fourth-rounder to see whether a discount was in the offing. The Broncos and Eagles were among those teams (both have GMs who like to investigate pretty much everything). The day clarified who was really in and who wasn’t.

In the end, McCaffrey ended up in San Fransico. But, it goes to show that though the Eagles may be undefeated, they are still committed to improving.

If Philadelphia would have been able to add an All-Pro running back, the landscape of the league wouldn't have been fair.

At 6-0 out of the bye week, Philadelphia is only trending upward.
