Greg did great work on this. I hope to add season and career records over time.

Typing this out really sucked so I'm going to do it with pictures.

Most Passing Yards

Most TD Passes

Most Completions

Most Attempts

Pictures don't work well for completion percentage and yards per attempt...too many pages of players with 100% for comp. % with most being 1 for 1 which doesn't count. For YPA, sort of the same thing, a lot of 1 long completions cluttering things up.

Wish there were more stat filters, like minimum 20 pass attempts, etc. Hopefully I'll remember to type those in at some point.
