At 22 and 200cm i would say the best of Griff is ahead of him, we have seen how the KPPs take longer to develop and most don't reach their peak until 24/25. So basically do you try and recruit a player at his peak and then pay top dollar and in addition lose some players to get him or do you draft a Griff type player early and just help him to grow into the player you want him to be.
I firmly believe patience is the key here and whilst it might upset a few i think perseverance is imperative otherwise he becomes another clubs gain and we end up the loser again. An analogy might be buying stockmarket shares, yes they have their ups and downs but ultimately in the majority of cases over the long term you get your money back and more, panic and sell when the market dips and not only do you do your money but you also miss out on further gains.
Griff's improvement is incremental, he wont become a champion overnight but i still believe the glimpses he has shown should provide people with enough confidence to stick by him and get some reward in the future for the club's investment to date.
