UPDATE:
I finished the last of the 8 challenges -- Notre Dame suddenly developed a case of fumble-itis, to my benefit. Also, as I learned on Reddit, pitches using speed option count as laterals.
The "reward" as expected is an 88+ pack, but there's an upgrade path with Sets that can slowly bring trade the 88 guy (I ended up with a non-BND version of the same guy I got from buying a pack earlier) up to a 93 version of somebody else. The sets use the pack guy you get plus one non-BND guy with the same rating. So, two 88s turn into an 89, that 89 plus another one turns into a 90, etc. So before you quicksell whatever you get (as I did earlier with my 86 guy from the first half of the challenges), check whether you have guy(s) to do the upgrade. I suspect this will also affect auction prices at least in the short term, or on Wednesdays for however many weeks this goofy challenge path runs.
