Depends on the size of the lottery. If it's one of those mega-power-ball type deals where there is a few hundred million, well then...let the good times roll.
First, I set up a scholarship (or several) for any US student who wins a junior national tournament to go to ANY post secondary school of their choice. I will pay one of the big time promoters to run.
Then I set up a "southeast swing" and a "midwest swing" of several tournaments that will, combined with the Joss and west coast swing, help kick start my national "tour" for pros. Of course I would hire a marketing firm to promote this endeavor, and I would hire a couple people who do nothing but secure sponsors/raise funding.
Oh. Yeah, My Majors would be US Open, Derby City, a new venue I will have built in Johnston City (because, why not), Turning Stone, and the Music City Open.
I would hire Joe Rogan as my Director of Entertainment and Lead PR spokesman.
Now, for the real stroke of genius. I build a 5 duplexes on a campus that surrounds a huge building that house 10-15 of the best 7 foot and 9 foot tables. I then pay SVB, Bergman, Skye, Thorpe, and corey and the amateur player of their choosing) 1 MILLION Dollars a year for a 2 year commitment to my program (the amateurs get 500k):
-Year -1 they live on campus and have to put in 8 hours a day on pool, either at the table, studying film, etc. I will have a rotating schedule of the greats (archer, strickland, varner, Efren, etc) to come in a have a "residency" where they will spar with and teach my pros and amateurs. All room and board will be paid during this time.
-Year 2- My pros are now ready to take over the pool world. I will stake them in every major international tournament in the world (for 60% of winnings). They will travel to the Philippines and lay it to waste. They will travel to China and be asked to leave because they are embarrassing everyone over there. Roy's Basement stays in the basement out of fear of my super turbo charged pros. Meanwhile, My amateurs back on campus have moved up to fill the pros spot and have selected 5 NEW amateurs to take their place. The cycle continues until Americans win the Mosconi Cup and the folks on AZB can finally rest easy.
