Is Jimmy Connors REALLY doing Andy Rod (and by extension, American tennis) any good?

Can the presence and influence of one boorish, arrogant, and obnoxious American (Connors) really be of benefit to essentially the younger version of himself (Rod)? Rod has always been rude and y - the clic "ugly American" - and now he's being mentored by the grand-daddy of them all? Is it any coincidence that Rod's unseeming on- and off-court behavior seems to have intensified since the introduction of Connors to his team? Profanity in press conferences, additional swagger on the court, and the now infamous "you don't bring sand to the beach" comment with Paris Hilton on his arm? Rod can't seem to play a match without staring longingly at Connors between EVERY point. Like a teenager clutching their precious mobile phone for dear life, this grown adult has now grown completely dependent on Jimmy Connors for constant validation. This is the guy we want representing American tennis? Did Rod need a new mentor, or does he really need a good etiquette cl?
