Upsets in Rio aside, both are poised to dominate their younger competition at the US Open, which starts Aug. 29.Serenas fountain of youthWith Serena and Venus Williams still so prominent that it can feel like little has changed in the past 15 years of womens tennis. But Serena might be even better today, a month shy of 35, than she was as a teenager. Shes gone from battling for titles against women close to her age (Martina Hingis and Venus) and older (Lindsay Davenport, five years her senior) to dominating against a much younger group of rivals who have yet to break through, mainly because of, well, her. If she can get past the shoulder pain that hampered her in Rio, shell aim for an Open-era-record 23rd major title. ?Djokovic: The older, the betterThe best players on the ATP Tour right now are also among the oldest. Djokovic, No. 1 at 29, is joined at the top by No. 4 Roger Federer (35) and No. 5 Rafael Nadal (30). His biggest threat -- second-ranked Andy Murray, whos been on a hot streak with recent wins at Wimbledon and the Olympics -- is one week older. But Djokovic, who has won five of the past seven majors, is especially dominant over the younger set. Only two players his junior have banked a major win during his career -- Juan Martin del Potro in 2009 and Marin Cilic in 2014, both at the US Open. Any upstart looking to shift the balance of power in Flushing will have some daunting history -- and hard-hitting elders -- to get through. ?

Every Tuesday, Wednesday and Thursday, we pose a question to a rotating panel of ESPN fantasy basketball experts to gauge their thoughts on a hot topic. Todays contributors are ESPN NBA Insider Bradford Doolittle and ESPN Fantasys Kyle Soppe and Joe Kaiser.While Klay Thompsons ridiculous 60 points in 29 minutes grabbed all of Mondays headlines, Memphis Grizzlies guard Troy Daniels continued his own hot scoring streak, racking up 29 points and 7 3-pointers against the New Orleans Pelicans. Injuries have opened up a larger role for the journeyman, who has responded with 19, 19, 31 and 29 points with a total of 20 3s over his past four outings. Is his scoring legit? Should fantasy owners add him for the short or long term?Bradford Doolittle: The scoring and shooting are legit. Daniels has been one of the best long-range shooters in the NBA for a couple of years. Unfortunately, the rest of his game is limited enough that hes always been a third-stringer. The instant-offense role the Grizzlies have been using him in is his ideal gig, and hopefully, hes opened some eyes with his outburst. There is nothing hes done the last four games that is out of line with his career numbers except for the key factor: Hes played more.As the Grizzlies gradually get healthier, Daniels role will become more inconsistent. Hes a poor defender, doesnt make plays well enough for more than spot duty at point guard and can swing to small forward only in very small lineups. However, Memphis short-term injury prognosis is ugly enough that they should continue to lean on Daniels for scoring. Even as they get guys back, it would be surprising if Daniels started gettinng DNPs once again, but his court time will be limited enough that he wont be an impact producer.dddddddddddd.Kyle Soppe: As is always the case, the true answer lies somewhere in the middle. No, Daniels isnt Stephen Curry-lite after scoring 60 points in his last two games, but the fantasy relevance is here to stay ... in the right situation. Daniels never has been given an extended opportunity, but in limited playing time, he has yet to show much promise in non-scoring categories.It doesnt help his case that the Grizzlies are functioning as the third-slowest offense, so counting on volume is dangerous to say the least. That said, the bump in playing time makes Daniels a strong contributor in points and 3-pointers for the foreseeable future. Daniels is an add in all formats, but expectations need to be tempered a bit -- there are high peaks and low valleys to come.Joe Kaiser: The scoring is legit. Anyone who can hit seven 3s in an NBA game has to be taken seriously as a shooter and a scorer, and Daniels always was regarded highly for his 3-point shooting while in college at VCU.What this all comes down to is opportunity, though. Right now, the minutes are there for Daniels (he played 44 minutes in the overtime win over the Pelicans on Monday), but as soon as James Ennis, Chandler Parsons, Vince Carter and Mike Conley return, you can expect Daniels to play fewer than 20 minutes a game off the bench. The right thing to do is ride him while you can right now, and be prepared to sell high if you get the chance. ' ' '
