lebron is the 1st domino...

lebron stays in miami or goes to cleveland...

carmelo is the 2nd domino...

carmelo goes to miami if lebron stays in miami
carmelo goes to houston or possibly chicago if lebron goes to cleveland

love is the 3rd domino...

love goes to houston if carmelo goes to miami or possibly chicago
love goes to boston if carmelo goes to houston

conclusion:

if we want love...

we want lebron to go to cleveland and carmelo to go to houston...

that is our best chance...
