Rio Olympics 2016: Williams praises Wales duo ahead of NZ challenge
Great Britain's assistant coach Gareth Williams has praised the efforts of Wales players Sam Cross and James Davies at the Rio Olympics.
GB go into Wednesday's final Pool C game against New Zealand unbeaten after wins over Kenya and Japan.
Welshman Williams says Cross "had a real impact" off the bench in those wins.
"James is physical in the contact area, more in this tournament than we've seen in the build up to it," he added.
"And that's a massive strength of his and it's exciting when he does get the ball."
Britain face New Zealand at 16:30 on Wednesday in the final match in Pool C with GB holding an advantage.
Japan beat New Zealand 14-12 in the men's tournament's biggest opening day shock.
Britain's men made it two wins from two by beating Japan 21-19 in a thriller in their second match.
GB had opened their campaign with a comfortable 31-7 win over Kenya, with Dan Bibby (2), Dan Norton, Phil Burgess and Mark Bennett all scoring.
New Zealand will be without Sonny Bill Williams for the rest of the tournament after he partially ruptured an Achilles tendon.
The top two sides in each of the three pools go into the quarter-finals, plus the two best third-placed teams.
