JURGEN'S THROW IN COACH

So today the news is that Liverpool and the ever inventive Jurgen Klopp have appointed a throw in coach to help his professional footballing squad with their "throw ins". In recent decades Ian Hutchinson (1970 Cup Final), Rory Delap, a Republic of |Ireland international, threw huge throws into opposition penalty areas relentlessly in the late 1990s and early 2000s) and Megan Campbell, yes even a lady from the Republic of Ireland, have made the news by creating goal scoring opportunities from the "harmless" throw in. Hutchinson by all accounts had an extension of his spine and was double-jointed in his shoulders, hence the ability to produce a windmill throw.
There are others of course.

Thomas Gronnemark, a Danish soccer coach will be brought into the Liverpool training ground a couple of times a month, on a part time basis.
He has worked with Schalke 04, Hertha Berlin and FC Midtjylland, showing off his World record 51.33 metres. He also coaches the Danish bobsleigh team (any mountains in Denmark?) and national athletics.

As you appreciate, attention to detail is vital at the top level! There are approximately 85 throw ins taken during a match, so defending or attacking throws are both important.
What if an opposing player stands within a metre of the thrower and jumps up and down?
What if the thrower lets go of the ball with part of his foot inside the pitch?
Why is the touchline called the touchline?
Can you be offside from a throw in?
Can you use a towel to dry the ball?
Can you score directly from a throw in?
Can the goalie pick up a throw in back to him?
Here's more on throw ins.
