The U.S. men's basketball team has given little cause for concern across its first two group-stage games, showcasing a ruthlessly efficient offense across wins against Serbia and South Sudan. The final Group C game comes on Saturday against Puerto Rico, and while Team USA has already guaranteed itself a spot in the knockout round, there's still plenty to be decided — and plenty for the Americans to work on with potential heavyweight matchups on the horizon.

What should the U.S. be focused on? Does Puerto Rico have any path to an upset? And can anyone predict Steve Kerr's starting lineups? Let's get into it.

U.S. vs. Puerto Rico preview: Players to watch, keys to the game

Will Joel Embiid see the court?

Head coach Steve Kerr responded to the controversy surrounding Jayson Tatum's benching by starting Tatum in the ensuing game against South Sudan. After kicking up another round of discourse by benching Joel Embiid against South Sudan, will the big man get similar treatment? Puerto Rico is also a bit undersized, although it's not quite as positionless as South Sudan. And it seems unlikely that Kerr would shelve Embiid for two straight games before presumably asking him to ramp back up for a quarterfinal game. So the question becomes: Will Embiid start, and if he doesn't, how will he affect the U.S. big man rotation?

How will the U.S. handle Alvarado?

I don't want to overstate things here; Jose Alvarado is hardly a superstar. But he is a legitimate NBA player, and he's capable of breaking down just about anyone off the dribble. It's unlikely that Alvarado can do enough to seriously threaten the U.S. in this game, but he's the sort of lead guard that the Americans haven't had to deal with over their first two games. Point-of-attack defense from the likes of Steph Curry and Anthony Edwards was a bit of a concern over the summer tune-up series, and how they handle Alvarado will be a good test ahead of potential matchups against the likes of Shai Gilgeous-Alexander and Dennis Schroder. If Alvarado starts cooking a bit, it could raise some alarm bells.

Can the U.S. run up the score?

The U.S. is guaranteed a spot in the quarterfinal and will almost certainly win Group C, but there is some incentive for the U.S. to win by as much as it can. Most of the quarterfinal bracket is selected by a random draw, but the two highest-ranked teams are put in a separate pot to ensure that they wind up on opposite sides of the bracket. Canada and XXX are already in the clubhouse at 3-0; for the U.S. to ensure that it remains in the top two — and avoid either of those teams until the gold-medal game — it will have to not only win but win by enough that it retains its edge in point differential. 

Can everybody get some rest?

The other upside to turning this into a laugher: The older members of this roster will have a quick evening and a chance to stay fresh ahead of when the games start to really count. LeBron James and Co. show no signs of slowing down yet, but every little bit helps, especially with Kevin Durant returning from his calf injury.
