LAS VEGAS -- It was hardly the classiest tactic, but trainer Ruben Guerrero injected plenty of intrigue into his son Robert's upcoming welterweight title bout with Floyd Mayweather Jr. on Wednesday.

After a boring thank-you fest disguised as a news conference in the MGM Grand's Hollywood Theatre, promoter Oscar De La Hoya invited Ruben Guerrero to the dais to say a few words. Virtually every other speaker had gone on in a monotone fashion, thanking every entity possible, name-dropping sponsors ad nauseum and predicting a great fight.

He ranted and raved like a madman, shouting about Mayweather's domestic violence conviction that forced the pound-for-pound top boxer to spend 57 days in a local jail last year.

Floyd Mayweather Jr. may fight again on Sept. 14 (Las Vegas News Bureau via AP)Two short emails released to the media Tuesday by Keith Kizer, the executive director of the Nevada Athletic Commission, seemed to ignite yet another dispute between powerhouse promoters Top Rank and Golden Boy.

In Canelo Alvarez, what we have is a strong, young, gifted fighter who is just beginning his championship journey.

But what was on display Saturday night in a super welterweight title unification bout at the Alamodome in San Antonio was much of what the young slugger from Mexico lacks.

In defeating sneaky southpaw Austin Trout , which is no easy task, Alvarez did enough to claim a victory on Showtime that was a much closer fight than whichever one most of the ringside judges witnessed (official scoring: 115-112, 116-111, 118-109). But hey, at least they got the result right.

For Alvarez (42-0-1, 30 KOs), he now has an opportunity to take a good look at himself and tally the things he needs to improve upon. At various times during the bout, his ability to cut off the ring, his footwork, his conditioning and his combination punching came into question. True, Trout had much to do with that, but if Alvarez wants
