Greenwood played did he not ??Eh, I get why we committed to it, as it was way too late to change it up, but the clock struck midnight on a flawed setup and ideology.
Also, losing McGovern and Greenwood* were big, seeing it was their inclusions which kick started Adelaide season in the back end plus the structure only really worked with McGovern as a third tall, seeing it was a team that ironically lacked an aerial threat which he rectified to a degree. Greenwood as well was a real 'ahead of the time' inclusion with hindsight, seeing putting a defensive shitwreckers in the middle, even with middling offensive ability has become the go-to method to generate a spike in performance as the year wears on.
Another one was playing hurt mind you. Smith was a loss as well.
