I honestly don't think it is that obvious at all.
You may be forgetting we're talking about 2019, with an increased cap and also when Thaiday retires, who is taking a fair chunk of said cap. At that point, we can weigh up who else we can do without, based not only on their performance, but also on the performances of the up and comers who will replace them.
We can't pay the amount being bandied about to Boyd, and we may lose Glenn, Mead and Sims on top of it, but I highly doubt we'd lose any more than that, and I truly believe we have those losses covered with the youth we have.
I am not saying we should bring Ash at all costs, but taking into account the skills he brings, which we do desperately need, I would have no problem at all with the above... zip, absolutely zero!
