We can't "overpay" him. We have pretty much a hard cap on what we can pay him, which is 105% of the average contract (early Bird contract) or the MLE - whichever winds up being more - but it's roughly about 10m per. Ideally he signs the early-Bird deal and we keep the MLE for another signing.
There's no reason to offer him anything beneath that either, because we are technically under the cap, it's just that Holmes or his hold will put us over. So it's just something we do immediately and hopefully nobody comes along and offers him 12 or 14 or something we can't touch.
I think, as there is level of subjectivity in player value, there is always someone who will say a player is overpaid or underpaid. And therefore we can overpay.
