This. Let's not argue who lost the better players here. Peters was just as important to them as Smith is to us. Hicks was just as important to them as Lee is to us. Zeke and Sproles had different roles, so comparing them is not useful--let's just say that Zeke is more of a cog than Sproles, as we saw last game.
The Eagle coaches and GM have done an excellent job of identifying payers who could step is and at least be serviceable, NFL players. Some have surprised--their corner play has been better than expected. think Cox is important to them? What happened when Cox was out for a few games...they put in Beau Allen and they didn't lose a beat. Beau Allen, Jaylen Mills, and Joe Walker were all 7th round draft picks. Let that sink in.
The Eagles wanted to shore up their RB's, so they get Ajayi. They now sign a tackle and LB for depth. We can sit here and pretend that the Eagles are just having a magical year, but the truth is that coaching and identifying the right players as backups are just as important as any "magic" surrounding that team this year. They went 7-9 last year and made a commitment to fix things. We went 13-3 and thought what, that we didn't need competent depth in case of injury? They are not 8-1 because they are lucky, but because they seem to know what in the hell they are doing.
