I don't have a problem with him making a buck if people are willing to spend money on the product. However, I feel like this has been attempted before many seasons ago by another user (who may not be as diligent as yatzr) who never followed through on his product and a small number of people probably wasted their money on it. I'm not in GD so I don't know anything about it. There seems to be a pretty decent following though.
I am against giving out too much to make things easier. Not the scraping tool, I don't mind that, but giving out equations that people use to rate players would eventually make the game rather vanilla. Everyone would have to devices to key in on the top recruits in minutes or seconds and there would be no advantage to actually searching for the best recruits. I sound like vandydave here and perhaps I've become old school, but I miss the days where things aren't spoon fed to everyone.
That said, I'd love to see some way to send out a coach's call to everyone on my watch list at the start of recruiting b/c that does waste a lot of time.
