Just to balance the too early discussion - whilst clearly if the offense warrants a yellow that’s what should be given be it the 1st or the 90th minute - however the better refs tend to sus out the tempo of the game early on as to is it necessary to stamp authority early. They also have a totting up system for persistent minor offenses before they finally reach for the yellow and you can see them explaining - “there, there and now it’s yellow” - probably for JJOT a good thing or he would see many more early baths!
I agree with this regarding sussing then tempo and also totting up.
On the flip side of that, the amount of subs that come on and then get booked for their first foul in the game is ridulous, when the same fouls frequently occur in the first half without bookings.
