Rory McIlroy- he comes across as a very arrogant & thin-skinned person as in 2011 when he called a former golfer turned commentator a "has been" for being critical of his play at an European Tour tournament.
Furthermore, it is my understanding that Monty has never won a single tournament on the PGA Tour. However, I feel he should make it into the World Golf Hall of Fame based on his play in the Ryder Cup and the European Tour. :)
What was wrong? IMO, it demonstrated that Rory was a first class jerk and lacking in manners!!! He needed to understand that he was playing on the world stage and stop acting like "a petulant kid".
And, if you know Rory, you should tell him don't bring "the name calling" to Augusta or they will send him to one of the course cabins he met last year as punishment OR banish him for life. lol
