Dylan Brown's record-breaking $14 million deal at Newcastle has been the talk of the NRL, but Parramatta coach Jason Ryles isn't surprised his half accepted it.

Parramatta have confirmed Dylan Brown will leave the club at the end of the season, with the five-eighth poised to join Newcastle in what will likely be the richest deal in NRL history.

Parramatta's Dylan Brown says contract security offered by Newcastle prompted him to leave the Eels for a 10-year deal with the Knights.

"I'm not talking about Dylan Brown," Adam O'Brien declared as he kick-started the process of being peppered by questions about Newcastle's record-breaking acquisition from Parramatta.

Some of the Hunter’s favourite sons agree Brown’s a great talent but question whether the Knights’ record signing can make the switch to halfback.

Newcastle's powerbrokers spent too much time debating if they could sign Dylan Brown, and not enough time wondering whether they should.
