You'll have to get over your obsession with one position.
Rampe - one position; Enright - one position; Shaw - one position; Laird - one position; Birchall - one position; Docherty - one position; Zac Williams - one position; Neville Jetta - one position ...
If you don't think Hibberd is good enough that's fine, but I'd lose the concerns over "one position". Although I'll add that he came 4th in their B&F in 2014, which was a year they played finals. The description "foot soldier" suggests to me that you're not overly familiar with the player. At 27 he's in his prime.
I've also never worried about a player's pay. I'll back the club to manage the finances within the salary cap.
