I'm hoping that Taylor will be that squad option.
Taylor is a superior LB to Manning (though that isn't hard). But as I've said before, I'd be underwhelmed if he was our first choice LB - and especially so if it's first choice LWB.
But putting Taylor aside, my train of thought was more that if Wellington's ability is only high enough to be a squad option, then it's not overly important as to whether we get him signed or not. If we weren't to sign him, we probably won't be regretting it later down the line.
