Running Backs Are For Suckers
The Eagles biggest weakness is their best feature. They don't need a running back.
Every NFL team sucks somewhere. With 53 players for 22 positions over 17 weeks holes are not emergencies, they're a fact of life. The key is to properly recognize and prepare for them. The Eagles have done so.
Consider the entire offensive roster. What does the depth chart look like? Wentz is an upcoming dynamo with acceptable backups. The receiver position went from frog to prince in an offseason. Tight end has 3 solid contributors. The offensive line is versatile, talented, and reasonably young. Again, you have to suck somewhere. You might as well suck at the least important position.
They key is to own it. By investing their resources literally everywhere else across the offense, the Eagles have owned it. They're preparing to be a pass first team that can attack with size and speed. They've eliminated 8 man fronts in turn. They have a blocking tight end in Brent Celek. He will make bigger holes. The backup center (Wisniewski) is better than the starting center. To say that the team has ignored the running back position is a fallacy. The problem has been solved by ignoring it.
Talented running backs are everywhere. They're making your coffee at Wawa and tweeting sick memes from the bus. Sub Smallwood out for Pumphery, give John Barchard short yardage work. Rinse and repeat.
This has happened with the Eagles before. Andy Reid ran through a comical number of overmatched wide receivers. However, he paid for a top line QB in Donovan McNabb, constantly developed linemen, and drafted running backs in the top three rounds to compensate.
What's important in a scenario such as this is to specialize. Have a short yardage guy. Draft a back that can be catch and pass protect. Develop a between the tackles player. After all, it takes 5 zords to build a Megazord, amirite?
I get the love for a "bell cow" back. However, when you consider the shelf life of the position, the balance of roster building, and the dynamics of the NFL a running back committee is the best approach.
So yeah, running back is a wart. And it's beautiful.
