I don't mind long throws per se, but I really do mind how long it takes (yes, even when it's Jack Robinson lining one up). It's increasingly mad to me that everyone is just okay with throw-ins taking around 30 seconds, in a game that is fundamentally about kicking a ball. Because I am petty I counted how long it took Rotherham to take a random throw-in on the halfway line (so not even in a dangerous area) in the FIRST HALF of our game last week - 28 seconds.
Throw-ins happen loads - there were 59 in the Rotherham game, 65 in the Hull game - and while obviously not all of them take 20+ seconds, I would love to see something like a time limit on how long you have to take one, eg 10 seconds that essentially starts from the moment the ball is returned to the throwing team. If it's not taken in time then it's essentially a foul throw and the other team takes over.
10 seconds should still be time to lob the ball into the box if you've got a specialist, just that you don't get to spend ages polishing it with a towel. If there's one thing I definitely don't go to football to see, it's someone cleaning a ball with a towel. Get on with the game!
