You might have heard some of the PGA Tour pros say the Blue Monster golf course is too easy after the WGC Championships at Doral earlier this month. I won't mention any names.

Rory McIlroy.

Well, maybe. New owner Donald Trump says he'll turn it back into a tiger with a multi-million dollar renovation.

But, it got me thinking. If the PGA Tour boys want a difficult golf course, we can accommodate them. Florida is chock full of golf courses that will make you wince, cringe and cuss before bringing you to your knees. 
So here are my top five choices for tough Florida courses that could easily host PGA Tour tournaments. The USGA ratings are for the very good, scratch golfers. The slope ratings are for the rest of us hacks.
Conservatory at Hammock Beach Resort: The longest course in Florida at a whopping 7,776 yards with a USGA rating of 78.4 and slope rating of 155. That's as high as you can go on the slope scale, golf fans.
Concession Golf Club: This course also has a slope rating of 155. It's a beautiful design by Jack Nicklaus with input from Tony Jacklin.
The Blue Monster isn't even the most difficult course at Doral. That honor goes to the Jim McLean course, with three of the hardest holes in golf leading off, as well as its own "Bermuda Triangle."
The International course at ChampionsGate is a wide-open, links-style course that will make all those Europeans feel at home. It plays hard, fast and firm when the wind blows.
Windswept Dunes: This is my dark horse, my underrated monster. This big, brawny and, yes, wind-swept brute in the dunes of  northwest Florida is one of the longest courses in the state with huge, tricky greens.
Let's see if they whine about any of these courses being too easy.
