Read Wikipedia:Publicity photos very carefully; the definition of promotional images is a bit narrower than Jaranda stated above, though all these HOF images don't meet those requirements either.  All of them are going to have to be removed.  Please consider going through and tag them all {{db-unfree}}  (see WP:CSD for more info) instead of leaving all of the work for others.  There have been numerous discussions of images on Wikipedia talk:WikiProject National Football League that might interest you, but the common thread is that there are very few football images on the internet that are suitable for Wikipedia.  Ideas about the fair use of magazine covers in articles that aren't about that magazine (or that don't have significant written content about the magazine) are currently in flux too.

I've said this several times before, but it's a good idea to check with others before making changes to a large number of pages. Wikipedia is a collaborative effort. ×
