What does good enough for Super League even mean?
Anyway, my opinion is of course he is, whether he would have the impact he has in the championship I don't know, he might actually thrive in a better team, this could be said of many players though, so I would go back to what does it actually mean.
If the question is, would it be worth a super league side taking a punt on him, yes is the answer. His attitude and conditioning are of Super League potential. He has carried our attack and forwards on occasions.
We should leave this until the top four is sorted though, no distractions, and no need to be discussed at this stage, other than to sign him up for next season so we can get a fee should one be applicable. He's a safe bet to get re signed early. Low risk in terms of his performance and potential to pay back a few quid should opportunity knock. The worst situation would be to lose him, no fee, and have him smashing us to bits dual reg'ing for another championship club.
