Jarrod was a bit of a disappointment. He suffered lots of injuries from memory, but despite, as you say, going hard in the air and on the ground, he seemed all too often to emerge from a contest without the ball - lots of bashing and crashing yet not enough ball collecting, whether in the air or on the ground. That's my memory of him anyway.Freddy reminds me of Jarrod Molloy. Goes hard in the air and at ground level. He's unlikely to take many contested marks, but if he can bring it to ground and also provide a contest and pressure at ground level, he'll be valuable.
My other memory is that we swapped him for Mal Michael who went on to become a star at Brisbane. Even still, I was more than prepared to like Molloy (played full back for Fitzroy, didn't he?), to be the best friend on the sidelines that he didn't know he had, but he just didn't seem to be around often enough and long enough to telepathically bond with him as I'd like to have done.
I just thought he was going to be so much better for us than he actually was.
