Possibly but more likely about the same I reckon. Bellamy was so far ahead of the rest of the coaching fraternity in terms of focusing hard on the dark arts etc - that is part of development of players. Winning the ruck - Storm were head and shoulders above other for ages and Smith cashed in. Could be wrong.
Well here's a list of players who came through the Storm's pathways, left the club and became better players elsewhere:
Atkinson
Auva'a
Drinkwater
Fa'asuamaleaui
Hampton
Hunt
Hynes
Mann
McLean
O'Neill
Tagataese
Tolman
Walters
Did they receive better coaching at their new clubs or were they always youngsters with NRL potential that were identified and poached by Melbourne's extremely well resourced junior recruitment apparatus?
There's also the likes of Croft, Kelly, Ieremia, Seve, Tonumaipe'a and Lumelume, who never amounted to much, despite the Storm's supposed ability to develop players. Every club is playing the numbers game with pathways recruitment, having successes and failures. But clubs like the Storm have a much better strike rate than other clubs. The fact they sign youngsters who chase opportunities elsewhere and thrive, regardless of going to worse clubs, is good evidence that they were always going to become NRL players (or better), and that Melbourne identified it and won their signatures ahead of rival clubs.
