Tom Tango has long been one of the top statistical analysts in the business. He coauthored The Book: Playing the Percentages in Baseball, which anyone who cares about the advanced study of baseball could benefit from reading, and his website is regularly updated with thought provoking and informative posts.
One of his projects is an annual fan scouting report.
Here is the gist of it, as explained by Tango:
What I would like to do now is tap that pool of talent. I want you to tell me what your eyes see. I want you to tell me how good or bad a fielder is. Go down, and start selecting the team(s) that you watch all the time. For any player that you've seen play in at least 10 games in 2014, I want you to judge his performance in 7 specific fielding categories.
Pretty much anyone reading this site has seen the Indians play at least 10 times this year, meaning you're qualified to weigh in on the defense they played. (The world needs to know how awful things have been!)
I know many of you feel the advanced metrics are missing something with Michael Brantley. Now is your chance to do something other than preaching to the choir. The outside world may not know that Carlos Santana has become a very capable defensive first baseman. Yan Gomes and Roberto Perez have both looked great behind the plate.
Those are some of my takes, but yours might be different, and this project has room for anyone who's been watching and paying attention. (Though there are a couple guys I think we can all agree have been pretty terrible in the field.)
Also, as Tango makes clear, you can submit responses for more than one team. If you watch the Indians every night, you've seen the other AL Central teams plenty, and may feel qualified to weigh in on some of those guys, etc.
