What is the plan for Eagles Running Backs without Miles Sanders?

On Friday, the Philadelphia Eagles Injury Report opened the door for a new set of questions about Head Coach Nick Sirianni's Offense and how he uses the Running Backs for this Sunday's game versus the Detroit Lions

With Miles Sanders ruled out, the Eagles are down to Rookie Kenneth Gainwell, fourth year Eagles RB Boston Scott, and former Pro Bowl Running Back Jordan Howard.  HC Nick Sirianni spoke about the Running Back situation to the media on Friday:

That answer by Nick Sirianni creates a new set of questions about this Jekyl and Hyde Offense:

-If Jordan Howard is getting reps with the first team offense, does that mean he is in there for Run Plays as a "Power Back" or is he just in there as a Blocker because he is the best Pass Blocker of the Running Backs on the roster?

-Without Miles Sanders, we saw Boston Scott get Seven Rush Attempts and One Catch while Kenneth Gainwell had Five Rush Attempts and Four Catches.  Should we expect a similar plan to use those players or will this Sunday's game plan be much different?

We know that under Nick Sirianni, this Offense has the fifth fewest Rush Attempts in the NFL, so does that mean we should just not get our hopes up when we see Jordan Howard on the field this Sunday?  Under Doug Pederson, Jordan Howard averaged 11.9 Rush Attempts per game in 2019 and Boston Scott had Five Rushing Touchdowns during the 2019 season.  So we know these guys are capable of carrying the load of a Running Attack, but with Nick Sirianni in charge, who knows what will happen this Sunday!
