I actually quite like Covell as a player and don't think he'll disgrace himself if he plays, but his selection seems a bit unnecessary with Inu in the squad who can kick goals. I'd have definitely preferred to see Perrett at fullback with Inu on the wing. I've disappointed that either Luke or Fein didn't make the team as well, I rate both Faiumu and Halatau (though Halatau has seemed a little off form) but neither are terribly creative hookers. It's a shame that we've never really found a top line replacement for Richard Swain there.
I'd go for:
1: Krisnan Inu
2: Taniela Tuiaki
3: Steve Matai
4: Simon Mannering
5: Luke Covell
6: Ben Roberts
7: Jeremy Smith
8: Roy Asotasi
9: Dene Halatau
10: Sam Rapira
11: Frank Pritchard
12: Louis Anderson
13: Shontayne Hape
14: David Faiumu
15: Jeff Lima
16: Fuifui Moimoi
17: Jeremy Smith
Playing Hape at lock might be a bit of an ask with him just coming back from injury, so if he doesn't seem up to that I guess I'd switch him to centre, bring Smith into the starting team and move Mannering to the bench. The team formation could move around a fair bit during the game really, with Mannering, Tuiaki, and Hape all capable of playing in both the forwards and the backline.
Whatuira can move into the team if Matai is ruled out. It's probably worth mentioning that I haven't watched very many Dragons games and can't actually remember seeing Stanley play, so that's why I picked Covell ahead of him.
I must say that I still don't understand why Koopu doesn't get a look in if he doesn't have some injury I don't know about. With the team we've got I'd be quite happy to see him in the forward pack.
