July 1 isn’t here yet, but the Dwightmare has begun anew. According to CBS Sports, Dwight Howard is going to give serious consideration to Houston and Dallas during free agency, and his return to the Los Angeles Lakers is by no means guaranteed: “Though Howard is adamant his free agency not be marred by the circus-like environment that surrounded his departure from Orlando last summer, word already has spread to multiple levels of his support staff that Howard re-signing with the Lakers is far from a done deal. With six weeks to go before Howard becomes an unrestricted free agent, the team that is said to intrigue him the most is the Houston Rockets, according to multiple people briefed on internal conversations surrounding Howard’s free-agent decision. The Rockets have a young star, James Harden, who has proved himself worthy of playing the leading role for the franchise; a budding 3-point shooting threat in Chandler Parsons; a defensive-minded coach in Kevin McHale; and Omer Asik, the kind of 7-footer Howard is believed to want next to him in the frontcourt. [...] The Mavericks represent another franchise that intrigues Howard, and Dallas is a minor transaction or two away from having enough room to sign Howard outright as an unrestricted free agent. Howard plans to explore all such options, and a person briefed on his plans said that there are ‘several’ teams the free-agent center is ‘going to take a hard look at.’ The clear advantage for the Lakers in their effort to re-sign Howard is the 2011 collective bargaining agreement, which allows LA to give Howard a five-year deal with annual increases based on 7.5 percent of his first-year salary in a new deal — which will be in excess of $20 million. Another team with cap room to sign Howard could only give him a four-year deal with 4.5 percent annual increases — the same arrangement Howard would be limited to if he agreed to leave via a sign-and-trade.”
