It was Gibson's last gift to Rugby League. Took over NSW for two series, in his first he blooded all these talented up and coming players and went down 3-0. Returns in 1990 and has the series wrapped up by Game II.
He wasn't finished blooding players that series either, NSW in 1990 had 8 debutants.
Wishart, Walford, Stuart, Roberts, G. Lyons, Toovey, Fittler and Sargent.
A fair contingent, at least half of them went onto have stellar Origin careers.
