Add to that mix work-horse back-rower Simon Mannering, impressive second-rower Tohu Harris and back-line stars David Fusitua and Solomone Kata.
The Warriors now turn their attention to who will partner Johnson in the halves next year.
Not only is Foran off-contract but so are youngsters Ata Hingano and Mason Lino. Neither are ready to start with the forward pack the Warriors are likely to run out next season so that means the club will look seriously at the remaining available halves.
It is a near-certainty that Johnathan Thurston and Anthony Milford will remain with the Cowboys and Broncos respectively - the two big name free agents left. It is likely that Moses Mbye (Bulldogs) and Trent Hodkinson (Knights) could be made available and the Warriors will consider the merits of both players.
If they can't attract one of those two players then look for them to go with youth at that point although signing an Australian youngster who is closer to first grade ready is a chance.
The next focus beyond the halves partner for Johnson will be signing a number of props.
All of the Warriors existing props - James Gavet, Albert Vete, Charlie Gubb, Jacob Lillyman and Toa Sipley are off-contract at the end of the year while Ben Matulino has signed with the Tigers. Only Sam Lisone remains contracted beyond next year. That means the Warriors need to sign four or five players to feature up front - some from their off-contract group but they will certainly look to bring one or two in from outside.
The Warriors would also look to maybe add another back-rower - Gold Coast's Leivaha Pulu has been rumoured - as well as an outside back or two.
The Warriors have plenty of cap space to play with although they do need to spend that across a number of players. They could add to that amount by releasing Tui Lolohea should he want to move on or if veteran winger Manu Vatuvei was to retire. The big winger has been named in an enlarged squad for this weekend's clash with the Roosters after recovering from a knee injury.
