Looking ahead to the NBA offseason, Gary (The Numbers Guy) Grinberg sees one move that could be detrimental for all parties involved: Deron Williams signing with the Dallas Mavericks.

"That would be the worst decision of the Mavericks and Deron Williams' careers," Grinberg says. "[Williams] is born in 1984 and Dirk Nowitzki's born in 1978. Rats and horses do not like each other. Rats and horses do not play well together."

In other words, 1984 is a rat year and 1978 is a horse year. The rat and horse combination is one of the most negative combinations in the Chinese zodiac. On paper, numerology says Williams and Nowitzki should be kept as far away from each other as possible.

Grinberg can back up his argument by using the example of the last time Williams needed to work with a Horse, Jerry Sloan, who was born in 1942.

"Think back to how Sloan and Williams were together," he says. "That would be the same thing if Dallas signs Williams."

The Numbers Guy also noted Tyson Chandler is a dog in the Chinese Zodiac. Dogs and horses display good chemistry together. Grinberg believes this allowed Nowitzki and Chandler to have good enough chemistry together in the Dallas frontcourt to help win the 2011 title.

Maybe the Mavericks should look to sign a talented Dog like Chandler over Williams if they want to make another run at a championship.
