INDIANAPOLIS – Defensive line depth.
Probably no position group heading into 2016 could see their depth fluctuate more next season based off injuries.
How much can the Colts count on Arthur Jones, after a 2015 preseason injury sent him to injured reserve for a second straight season?
Will Henry Anderson be ready to go in Week One, some 10 months after he tore his ACL in early November?
Those questions likely won't have answers until Training Camp nears in July.
An answer is needed soon though on free agent defensive tackle Billy Winn.
The Colts traded for Winn just prior to the start of the 2015 regular season.
For 12 games and three starts, Winn provided the Colts necessary depth along the defensive line before a torn rotator cuff placed him on injured reserve in December.
Winn is the lone defensive line free agent for the Colts.
A sixth-round pick by Cleveland in 2012, Winn has started 21 career games.
While a starting role for Winn in Indianapolis isn't expected, the Colts could use his depth and versatility with the uncertainties of Anderson and Jones.
In 2015, the Colts improved their defensive line depth, but there's always room for another body or two across that unit.
