I've looked up Sheens's first interview after becoming coach - I assume you mean this one: https://www.2gb.com/podcast/tim-sheens-confident-of-future-success-for-wests-tigers/. He talks with enthusiasm about the juniors coming through, noting that they are 1-3 years out. At no stage does he say the club is sacrificing the present for future success. How would that even work? The club is, and has been, investing in pathways: this is a good thing and it should produce success in the long term. They also just signed a bunch of first graders a year ago. Juniors aren't using salary cap and there's nothing to stop a club having a good first grade side and good juniors - these things aren't mutually exclusive and in fact I'm not sure how it would be possible to make them so.Tim Sheens said as much in his first interview when he took over as coach.
We have also released several players who would still be in our top 13 over the last few years only to end up signing no one. It’s always freeing up space for next year, but next year never came.
To your point, freeing up a bit of space in the salary cap for next season is not the same as always looking 2-3 years down the road: it's freeing up a bit of space in the cap for next season. You're more than welcome to say we've recruited badly; I'd agree, of course.
