Stevenson Set for Lead Role in Patriots Backfield, But Overall Depth Remains a Concern

Stevenson is expected to be the starting running back after performing well as a rookie.
Backup running back options are unproven, though Montgomery may contribute if healthy.
Rookie Pierre Strong Jr. has potential but needs to prove himself in training camp.
The offensive line should be improved compared to last season.
The Patriots may still look to add a veteran running back for depth due to concerns over lack of proven talent behind Stevenson.
