People will disagree given Izzy's 2013 form, but I've always thought and said on this forum that Karmichael would make a better rugby union player then Izzy. They are two distinctly different style of players though, its like comparing apples and orange's when you look at their actual skill sets and physical attributes.
Karmichael is a playmaker with great vision, and whilst he played fullback in Rugby League he was always filling that 2nd playmaker role outside of Lockyer, no doubt he would have moved to 5/8 had he still been at the club following Lockyer's retirement.
If the Reds were to chase him(which i don't think is going to happen) it would be for the fullback position, but ultimately he could play 10,12 or 15 if needed.
Given that, the Rebels would be the better destination considering they must have space under their salary cap and they desperately need a 10.
