With no ruck rookies, ordinary R/F coverage, or more unknown R/F coverage I should say.....well, to me it is a little crazy. Yes we can spruik on all we want about what benefits it can provide on other lines but given guys like TBC and Leuey are injury prone and even paired with someone like Maric or NN who we know are susceptible to ongoing restrictive conditions, what are you going to do if one or both go down.
And for TBC in the forwards is not cover, it's adding another problem.
But good luck - make or break and I hope you use your extra coin wisely.
