Will monty not be a reserve if people pull out???

I thought Arnold Palmer n Jack Nicklaus werent playing this year!!!
Also I thought Padraig Harrington pulled out due to his fathars illness!

I think past champions should be allowed to a certain level. maybe the next 10 - 25 years after they win it!!I think past champions like arnold palmer should use they're own judgement and realsie that the decent thing is to not play and allow the tournament to be for the top players!
