I don't know what you guys have seen in Adams, but I see someone who works hard for the team, creates space for the central striker and scores between 5 and 10 goals a season. In other words, qualities that precisely none of our current squad have.
It's the fact that you need to use your recruitment to improve moving forward. If you invest in a player who is over 25 they have to really offer something different. Adams runs around and struggles to score, hence Southampton are always down near the bottom with us. We will then be lumbered with Adams on wages far beyond being commensurate with his actual ability and having spent a lot of money on him. Then it will be rinse and repeat all the time. A circle of ??.
There are players out there who allow us to grow as a club and invest smaller fees that we make back/make profit on. Signing players like Adams because we have set ourselves such low benchmarks is exactly why we have been poor for so long. In my opinion we have made a major mistake in signing McNeil, but because of his age we should be able to make back roughly what we have paid for him at some point. He also has age on his side to improve, though I think it unlikely.
Finding good players from unexpected places and not your relegation rivals is the whole point of a recruitment team.
