I like Mike Bishay but I don't believe he has done enough to displace Moore or Cunningham.
Moore has made around 100 metres a game, averaged around 33 tackles and 20 attacking runs per game and has set up 4 tries.
Cunningham has made a strong impact from the bench, making over 7 metres a run and has made 6 tackle busts as well as running well from dummy half and about 15 tackles from limited game time.
Both Bishay and Gigot were anonymous at Widnes and whilst Gigot was much improved versus Salford I don't think the stats support Bishay as being better second time out.
His production has been minimal in fact with just 3.67 metres averaged and 0 tries, 0 clean breaks, 0 try assists, 0 offloads, 0 tackle busts and just 3 runs from dummy half and 4 marker tackles with only 42 metres made per game.
He needs to get much more involved in the game when he next gets his opportunity, which may come soon if Moore is moved to halfback given the possible switch of Farrar.
