What sort of crap list is this?
Very convenient to just ignore players that debuted under BA, or say he played no part in developing them. BA was at the club before he started as head coach.
Every club signs players from outside.
Players who debut for a club might well get poached by another club with the lure of opportunity/ more playing time/ higher salary (etc)
Players who debuted under BA, and played a significant amount of first grade (whether for the Eels or elsewhere):
Tepai MOEROA (2014)
Pauli PAULI (2014)
Manu MA'U (2014)
Daniel ALVARO (2015)
Bevan FRENCH (2016)
Oregon KAUFUSI (2018)
Reed MAHONEY (2018)
Marata NIUKORE (2018)
Jaemon SALMAN (2018)
Ray Stone (2018)
Dylan BROWN (2019)
You could make a strong argument that he developed players like Edwards, Gower, Gutherson, Terepo, Radradra, Jr Paulo, Sivo, Pritchard, Brown, who had played a handful of first grade games, or whose games improved greatly when Arthur took over their development.
[[There are probably more names, but that's all I could think of.]]
