Not in my eyes along with the eyes of 150 players anonymously polled in 2019.(in fairness to Fainu that poll may or may not have taken in the whole season)
For a player that has an average passing game, average at best defensive qualities, showed no real kicking game, no leadership qualities, no energy to rush out of dummy half defensively or be one of the leaders in kick chases sometimes, fatigued big time when the intensity was up beat, this is not the attributes of a top 5 hooker.(even for his age and experience)
For the right price Fainu is a keeper, but he most certainly isn't a player worth keeping on the books for 2yrs in the hope he either comes through the court case ok or off the back of "future potential" that i think is well over exaggerated beyond belief.
Plenty of other positions to sure up to make us a premiership threat along with depth before we should worry about a classy dummy half to capitalize on these good foundations.
Many hookers in the competition are making a name for themselves off the back of the team performance not as a result of them being the reason of that up tick in performance---to me this suggests you are better off focusing on other areas and a classy hooker completes the equation.
Not saying a top line hooker is not necessary as they can make a big difference, more a case of getting our priorities "acquisitions/retention" right before worrying about a hooker.
So many hookers have come out of nowhere and did a good job in teams with a good playing roster, along with good playing rosters have adapted well to not having their starting hooker.
