You sound like a selector, or my dad lol, who likes playing a scout following growth of young players with potential and takes satisfaction when some kids come through.
I grew up in the Blackadder/Smith/Deans era, we didn't like AKL, they didn't like us (rugby wise), John Hart picked a bunch of AKL players and Cantab boys like Toddy, Angus, Mayerhofler, Berryman, Lily are missing out on even the wider squad when we won 3 in a row, and that disastrous 98-99 period and Taine Randell was in a heap of sh*t too as the cap of the worst AB team...then that bloody Carlos gesture to the Chc fans after that 100m try...I think that's the psychology behind it. Then a the whole AB team was made up of Cantab players in the Richie and Dan era, and we won like another 4 titles, and communication got better, people move, media reports less hate between Cantab/AKL, earthquake, and the fact that AKL has been awful the last few years that kinda killed the rivalry and people starts to care for the ABs more...I think
