I have some comments to make your file better.
Seems you did not update all teams GK's. For example Toronto's GK are all in 50's, way too low.
Curious how you came up with ratings. I compared the highest speed guys on sofifa.com for MLS teams around 90 speed, and your file had a few in the 70's for those guys. Giovinco on Toronto is 79 speed in your file but on sofifa he is upper 80's. Thats just an example but there are more like this.
Regarding naming format, most players are named like C. Dempsey in PES, but your file has A LOT of names fully spelled out. For example your file spells our Harry Shipp when it should be H. Shipp. Again, many players are spelled with full first and last name, which doesnt follow PES format.
Thanks and keep up the good work.
