You kinda do, you get credits for players who came through your academy, though do sort of agree that maybe more should be done for proper senior players who have been there their whole careers - maybe scale that payment up over the course their career or something
I'm not sure if Saints not offering a big deal would be cap related though, in this case - they seem to be more cautious about his arm injury (and will know more about it than anyone) and I'm not sure if they actually spend up to the cap? Certainly feels like their outgoing players massively outweighed their signings last year. They seem more interested in breaking even/trying to turn a profit than spending as much as they're allowed to and hoping for the best
