I think it's presumptuous to compare chiesa to some of these legendary sinecures.
He's got to come back, look good for a couple games, split the fanbase, engender sympathy and hope, get reinjured, and repeat at least three or four times. The man is completely unproven at this so far. You can't just go handing out comparisons to some of these wastes of space, he might only be unremarkably useless.
