Mediocre series
"A Football Life" tries to present itself as the NFL Network's answer ESPN's "30 for 30" series. However, after watching many of it's episodes, I can only conclude that it is a very mediocre series. It is more on the level with ESPN's older series "Sports Century" and its in-house competition with "30 for 30" called "E:60" (no doubt created because ESPN wanted its own self-developed series to compete with the Bill Simmons-created "30 for 30").
"A Football Life" just scratches the surface of the topics and people it pretends to a deep dive on. Just watching the Warren Moon and Randall Cunningham episodes, you can see how quickly the filmmakers want to gloss over all segments of their subject. They spend 30 seconds talking about Warren Moon's time in Canada, and about 2 minutes talking about his career in Houston after his rookie season. The producers are trying to cram as much as possible into a 1 hour episode without digging into any depth on it. "A Football Life" needs to do what "30 for 30" does: either cutout some of the extraneous material to focus on the deeper story, or expand the episode to 90 minutes to 2 hours to give the subject the treatment it deserves.
Alas, the producers and filmmakers for "A Football Life" just aren't near the quality of the ones for "30 for 30", and it shows in the final product.
(As a side note, NFL Network's "America's game" does achieve that level of quality that "A Football Life" wishes for)
