Considering that Dick's selection sucks, that their prices are sky high and that their employees don't know jack about our game, I'm not losing any sleep over them being in the DG business.
If anything, what I've discovered is that as people who buy their initial discs at a Dick's or Academy or Wal-Mart or some similar store make their way to a local course, they run into folks while they are there who are members of the local club, who not only know the discs, but end up buying their club stock from one of the biggest online vendors in the country, can get them access to most any mold available from any manufacturer, in any weight the player desires, and get that disc to the player about $2-3 cheaper. As the number of "in the know" people increases, so does the likelihood that the next batch of uninformed people who buy their initial discs at big box stores are going to run into them.
