The long sleeves would hinder the players a little these days. Any player in the last 2-3 decades has short sleeves. I understand you want it more authentic but it shouldn't go so far that the players have extra cloth hanging on them that they don't want there.
Also, they don't have the tiger on the sleeve like in the 80's and 90's so that helps it look more like the 60's.
I think it’s funny that you can’t say anything on this forum without getting the gears. You are more than entitled to your opinion and can say what you want but jeez, if you have a problem with something I said, write it on that thread or PM me.
