Sign who? It may - in fact - be more complicated than you think. Look, I'm not saying that we need to keep this guy - just that I'll admit that I'm just a fan with limited access to the full wealth of data that goes into a decision like this.
Fans have very short fuses in general. A cornerback gets burned for a big play - 'cut him!' Special teams allows a big return (or two) - 'fire him!'
On multiple occasions, multiple fans on this forum and others have called for the jobs of McVay, Sneed, Stafford, and others. I'm glad we kept them. I'm glad we kept Raheem and his firing is called for almost weekly here.
Yes, 2 missed extra points is bad - and it may indeed be time to look around - but before you let a guy go, you know who is going to replace him.
