He isn't injury prone, he's had an Achilles injury that went south.
You wont find more injury prone players than Miller or Marcus. Miller is always injured without actually playing and Marcus has been out for long spells multiple times.
Money aside, i'd take him over both, also over Minozzi. The killer is he's away with England, for that reason plus a decent salary, i'd have to pass, but only for those reasons.
I doubt he'll go aboard, it's a misconception that it's $ utopia, especially given the 250k he'll earn a year with Eng....
He's the kind of player you have to make space for, be interesting to see where he end's up..I can see a fit at Saints, they'll be losing Bit T who's on a wedge apparently, plus Collins may be out of contract...but that's just a guess.
