Hargrave is a terrific shot for goal, there aren't many he misses, if he sneaks forward and has a few seconds to way up the situation he generally finishes well both on the run, and snaps.
Its been very rare that we have ever played him as a forward for any length of time - if we didn't have Johnson I think he could probably be a reasonable full forward, but would need space to lead into etc
We may miss him his kickouts as the major reliever to Gilbee, but I guess Griffen may pick up some of that slack also.
