Cheating, no.
It's a pre-season game, and those can be valuable to try things out and learn. In this case, spamming the one play means the other side win 147-0 but learn nothing.
There could be plenty of valid reasons for why what happened happened, ie editing plays and missing putting plays back in (done that one before...), maybe testing a new rule which was badly written.
If it was a regular season game, post season game then I'd view it somewhat more seriously, as there are tangible effects - inning/losing a title, draft order etc.
Just a friendly reminder that whilst pre-season is for trying things out, be mindful that something like this can cause the opponent to miss out on a game for trying things out. The penalty for spamming the same play is so great, as seen in that game, the opponent has no idea if things they wanted to assess in that game worked or not.
But no, I don't see that as cheating.
