Deletion of List of Major League Baseball records considered unbreakable

Comment: In reality, there are only records that are highly unlikely to be broken given today's conditions. However, conditions have changed throughout Major League Baseball history, and so virtually all records could be broken. Both Bill James and Baseball Prospectus, as I recall, have written about this in the past year. I don't believe there is a sufficiently well-founded central thesis for the concept of records that are considered unbreakable; each record requires its own explanation of the state of the game in the context of the achievement, why the record is difficult to break today, and what conditions would have to return (or be introduced) in order for the record to no longer be considered unbreakable. As such, I think the list is in danger of being a list of |non-encyclopedic cross-categorizations. I suggest that the articles for each achievement in question be expanded if necessary to include reliably-sourced discussion of how the changing conditions of MLB over the years have affected the ability to set new highs/lows for the achievement

Comment: This brings to mind List of movies considered the worst ever.  If you can find a |reliable source that a record is unbreakable, then it belongs in the article.  If it's just some fan's ideas, whether based on sabermetrics or tasseography|tea leaves, it should go.  If there are no reliable sources in support of any of the material, then delete the article
