Jonathon Brown was again pole-axed on the weekend charging back into an oncoming back to take a grab.
He suffered facial fractures and will be out for the rest of the season.
Courage is something Browny is noted for, but where is the line between courage and insanity?
The following scenarios could have played out yesterday:
1) Kick comes in, Brown chases ball back with flight, tries to mark it, gets smashed by the oncoming pack of players and is out for the season, or
2) Kick comes in, Brown chases ball back, but waits for contest from pack and decides to crumb instead, plays rest of game, plays rest of season etc etc.
Yeah, Brown is the epitome of courage but what was yesterday's act of courageousness in aid of?
What's your thoughts?
