I liked Thaiday. He has for mine genuine ball playing skills, and can run good lines.
Once upon a time.
Thaiday is overweight. He is a liability. He is a disgrace to the Broncos fitness and conditioning team. He is IMO one of the easiest forwards to tackle. He rarely breaks through the advantage line. He has no serious strength or power in his running.
For that reason alone, playing him at prop is a MASSIVE MISTAKE
For example, Lama Tasi is 189cms tall and weighs 106kgs
McGuire is 180cms and weighs 107 kgs
Hannant is 184cms tall weighing 107 kgs
Kennedy weighs 118kgs but at least he is 191cms tall
Corey Parker - 188cms tall and around 102kgs - we know how many metres he makes. Strength, power and determination
Thaiday is 181cms and weighs 112kgs. He needs to be around 106kgs max. 106kgs of muscle, not blubber
Only then will he be able to play as the damaging, wide running back rower he once was, and should be.
IMO, if form (which includes fitness) is a selection criterion, if he doesn't make a proper playing weight based on lean muscle, he ought to be on the bench at best, QCup otherwise.
