When referring to depth on any player, does each position on a football team have a back-up in place, or can depth be drawn from the practice squad?
Quick, my wife ask me this question and I said I'll get back to her.
That depends on what she's really asking.
In one sense "yes" in another sense "no".
For example, the game day 46 man roster might have 7 O-Linemen, as was the case in week 6 with Spriggs and Light inactive. Bell can play OG or OT, Patrick OG or OT, and somebody is the emergency backup at C, possibly Patrick who got some snaps there in preseason or McCray. So, all positions have a backup. However, while two injuries are covered three are not. In the event of three injuries, I suppose Lewis is an option at OT with a line shuffle, of course not something you'd ever want to see but certainly in the realm of possibility. A 4th. O-line injury? Who knows.
PS represents the deep bench. Injuries might necessitate the promotion of a guy from the PS to serve as a backup, which is more likely as the season wears on and street FA options are slim. A player who has been working in the system on the PS might be viewed as a better option than a street FA with some kind of resume who would have to acclimate to the system in short order.
Of course, the Packers just worked out a 1/2 dozen street FAs, all with some or a lot of roster experience, most former mid-round draft picks. What Gutekunst envisions is hard to say, but I believe all but one of them still have PS eligibility.
