Vaealiki was never intended to be released.
Wigan only went after him because the failed to get Gasiner. They would've approched Lex but there was no way Parra would have signed over the cap just because Lex would get sign IF Wigan failed to get Gasnier.
Dykes may well be to get under the cap but in saying that.
1) Parra were under the cap for this year even before Lyon left
2) Lyon leaving drops the Eels another 250K under the cap
3) Other players who are off contract would also leave eg Stapleton, Hopkins, Pearson, Langi etc while each wouldn't be on that much when combined it could get to a decent amount.
4) Most of these players will end up being replaced by rookies in the top 25 guiys like Mateo, B.Smith, Afamasaga and O'Dwyer and in most cases on less then the players they replaced.
All up just popping nuimbers out no real proof this is the case
Jan 1 2004 - Parra 200K under the cap
March 20th 2004 - Lyon leaves Parra now 450K under the cap (out 1 player)
June 2004 - Parra sign Riddell (270K), TAhu (320K), Morrison (300K), Stringer (220K) and Robinson (100K) total (in 5 players) = $1.210m - 450K = 760K
They don't re-sign (from the top 25) Hopkins (120K), Pearson (120K), Stapleton (130K), Kativerata (85K), Peek (100K), Thorman (140K) (out 7 players) = 695K - 760K = 65K
July 2004 - Parra release C.Armit (90K) (out 8 players) - 65K = 25K under the cap.
Parramatta then release Vaeaiki to Wigan his entire contract is paid off so nothing gets counted under the cap for the Eels 200K, and Dykes of his 300K deal Sharks pay 220 leaving the Eels with 80K so Parra "pick up" another 220K of cap space.
Total Cap space left = 465K
Top 25 count = 22 players still need 3 more
C'mon down Ben Smith (20K), Feleti Mateo (20K) & Jack Afamasaga (20K) = 60K
So, with a top 25 all set Parramatta are still 400K under the cap.
