They need to keep moving the goalposts as Tua keeps proving them wrong.
The need to be right in their view that Tua sucks seems to trump all logic now and they grasp at anything rather than look at it logically and realise the Dolphins have a top 10 QB who keeps improving.
Nothing Tua does will ever be good enough for some.
They are secretly Alabama haters or just don't like someone with Samoan heritage.
