The Storm and Cowboys got their campaigns off to solid starts with first-up trial wins and they'll both want to keep rolling when they meet at Casey Fields on Saturday.
Youngsters like Nicho Hynes and Tino Faasuamaleaui starred for Melbourne as they beat the Warriors 18-16 in Palmerston North last weekend.
Meanwhile, star signing Valentine Holmes had a decent cameo and rookie hooker Reuben Cotter excelled in North Queensland's victory over Brisbane by the same scoreline.
Storm: 1. Ryan Papenhuyzen, 2. Suliasi Vunivalu, 3. Justin Olam, 4. Marion Seve, 5. Josh Addo-Carr, 6. Cameron Munster, 7. Jahrome Hughes, 8. Jesse Bromwich, 9. Cameron Smith, 10. Tui Kamikamica, 11. Felise Kaufusi, 12. Kenny Bromwich, 13. Dale Finucane. Interchange: 14. Harry Grant, 15. Tino Fa'Asuamaleaui, 16. Max King, 17. Albert Vete, 18. Tom Eisenhuth, 19. Darryn Schonig, 20. Nicho Hynes, 21. Brenko Lee, 22. Ryley Jacks, 23. Cooper Johns, 24. Chris Lewis.
Cameron Smith, Cameron Munster, Josh Addo-Carr and Jesse Bromwich headline a powerful Storm squad. Marion Seve and Justin Olam will continue as the first-choice centre pairing as Craig Bellamy looks to settle on his team to face the Sea Eagles in round one. Brandon Smith (facial fracture), Nelson Asofa-Solomona (hamstring strain) and Christian Welch (knee rehab) are the only three big names missing.
Cowboys: 1. Valentine Holmes, 2. Kyle Feldt, 3. Esan Marsters, 4. Tom Opacic, 5. Justin O’Neill, 6. Jake Clifford, 7. Michael Morgan (c), 8. John Asiata, 9. Jake Granville, 10. Jordan McLean, 11. Gavin Cooper, 12. Coen Hess, 13. Jason Taumalolo. Interchange: 14. Reece Robson, 15. Shane Wright, 16. Francis Molo, 17. Corey Jensen, 18. Mitch Dunn, 20. Connelly Lemuelu.
Captain Michael Morgan was rested against Brisbane but lines up this week for his first game of 2020. Scott Drinkwater has been rested after picking up a minor pec strain against the Broncos. John Asiata and Gavin Cooper have also been named for their first hit-outs of the season. Josh McGuire is unavailable with an MCL injury suffered at the NRL Nines.
The big question
Storm: Can Harry Grant take his chance? Brandon Smith's injury is likely to give the promising young hooker a shot off the bench in the early rounds. Grant was outstanding in last week's trial against the Warriors and he'll be determined to show that he deserves to remain in first grade.
Cowboys: Can Valentine Holmes hit the attacking switch? The Cowboys' new No.1 was solid but unspectacular in his club debut in the rain in Cairns but he should get more minutes this time around as he looks to fast-track his trip back to top form.
