NFL Superpro is the sort of comic that gets no respect from the fanboys. And frankly there's a lot of reasons it shouldn't, but I remember this NFL tie-in comic with some kindness. I was in a full-on Marvel completist mode at the time it debuted, so I necessarily checked it out. I found that it was competently done, no less so than the myriad Spider-Man and Punisher books that littered the stands at the time, and it was drawn by a real hero of mine - Jose Delbo.
Delbo drew some dandy comics over the years for Dell and Gold Key and others. I first chanced upon his work on Charlton's Billy the Kid, and later noticed his professional line work at DC on things like Wonder Woman.
Delbo is one of those reliable pros who could tell a story with economy and skill, and who I'm guessing likely never missed a deadline. Seeing a guy like Delbo on any book is enough to make me give it a chance.
Was NFL Superpro a good comic book. Not really, but it was a diverting entertainment. I cannot imagine the "No Fun League" licensing such a project today.
