When asked if Chase Coffman could find himself on the team's practice squad, the Enquirer's Joe Reedy said that it's "possible if he clears waivers". I myself believed that Chase was eligible, so I didn't think much else of it. Still, with my obsessive tendencies, I wanted to be absolutely certain. Article XXXIV of the collective bargaining agreement reads regarding the practice squad:
Section 4. Eligibility:
(a) The practice squad shall consist of the following players, provided that they have not served more than two previous seasons on a Practice Squad: (i) players who do not have an Accrued Season of NFL experience; and (ii) free agent players who were on the Active List for fewer than nine regular season games during their only Accrued Season(s). An otherwise eligible player may be a practice squad player for a third season only if the Club by which he is employed that season has at least 53 players on its Active/Inactive List during the entire period of his employment.
(b) A player shall be deemed to have served on a Practice Squad in a season if he has passed the club's physical and been a member of the club's Practice Squad for at least three regular season or postseason games during his first two Practice Squad seasons, and for at least one regular season or postseason game during his third Practice Squad season. (A bye week counts as a game provided that the player is not terminated until after the regular season or postseason weekend in question.)
The CBA defines an accrued season as six or more regular season games on the team's active/inactive roster, Injured Reserve or on the PUP list.
This is where confusion, at first, set in. "Free agent players who were on the active list for fewer than nine regular season games during their Accrued Season." Merely defining what is an accrued season, in which Coffman did successfully accumulate, doesn't mean he's ineligible. The statement of the practice team eligibility that reads, "free agent players who were on the Active List for fewer than nine regular season games during their only Accrued Season", says that Coffman must be on the team's active list during game day during his only accrued season.
Coffman's lone accrued season, he was listed as inactive on the team's active 53-man roster through the team's first 12 games. He spent the final four games on Injured Reserve. Yes, he had an accrued season. And in the accrued season, Coffman wasn't on the active game roster. Along with Reedy, Chick Ludwig writes that everyone that was waived, save for five players, are eligible for the practice squad, including Chase Coffman.
