If he's bulked up a bit and has more confidence in defence he could be a great option. Was always rapid, massive boot and good distribution skills.
'My leg snapped': Brumbies recruit Jesse Mogg back to Canberra after 651-day injury
Doesn't sound like a great incoming player to return on a 2 year deal for a 32 who had nearly 2 years off with a broken leg.
I had the same thought as you did hence the post.
Yeah read about it today, wasn't aware of it, but the article suggested its healed up and has been for a while, and he still has some serious pace despite it. I doubt McKeller et al wouldn't have been aware of it in the signing process, and the fact they decided it was a good signing (which the Brumbies have been very good at evaluating over the years) is enough for me. He might not crack the Wallabies again, but unless he's fooled the Brumbies medical staff and bluffed his fitness tests, I think he'll be ok.
Certainly at least on the level of Mack Hansen, whom he's replacing.
