Well let's look at it, who would attract interest from elsewhere for the contracts they are on:
1. Milford (Yes but would have to be heavily subsidised)
2. Oates (Seems not necessarily given he just re-signed)
3. Staggs (Absolutely but reportedly just re-signed and Broncs cannot lose him)
4. Glenn (Yes he has interest for sure, loves the club though thankfully)
5. Isaako (Yes he would have interest for sure)
6. Boyd (Haha, no seriously, ahahahahahahahaha)
7. Turpin (Yes, he had interest before re-signing)
8. Lodge (Yes, just re-signed but would attract offers for sure)
9. Macca (Seems some lukewarm interest but would need to be subsidised and seems does not want to leave)
10. Haas (All clubs, sports and sides in league, rugby, probably NFL and wrestling would want this kid, everyone would through the chequebook at him, he is going nowhere)
11. Fifita (See above)
12. Gillett (If he wasn't broken, would absolutely attract interest but he looks like his retirement is imminent)
13. Joffa (Just re-signed but he would definitely attract interest)
14. Segeyaro (Hard to get a contract when you may well be suspended for the rest of your career)
15. Flegler (Yes, not yet re-signed and would have a number of clubs interested BUT not on big money currently)
16. Carrigan (Yes has had and would have a number of clubs lining him up, has re-signed thankfully)
17. TPJ (Absolutely would have clubs interested but has re-signed and does not seem to really want to go anywhere)
So a number of players would attract interest if available.
