A post earlier in the thread...
To be challenging them, you need to start by matching what they do against the other 10 teams in the league. Once you've done that it comes down the OF games alone. McInnes hasn't been that far off that, easily being the best of the rest with arguably, an inferior squad than ours. In fact, this season, outwith their game against each other they are pretty much identical.
What McInnes is doing is achieving a consistency we desperately need in the same league. So, here we have a manager, in our league, doing what we need to be doing...i.e. achieving consistency that allows his team going into head to heads with them that actually mean something. OK, they're failing in those head to heads, but at least he's taking them to a position that's exactly where we need to be, and it strikes me as curious that some of our fans don't think it's worth a shot. With the greater resources being Rangers manager brings then the opportunity to challenge with McInnes looks a very attractive proposition to me.
Aside from that, he's pulled in players who some have seen as ordinary and turned them into good players that are attracting interest from elsewhere (including us), such as Lewis, Logan, Rooney, McLean, Shinnie and started bringing through youngsters like O'Connor and Wright.
He's a guy that knows what he's doing in Scotland, has improved his teams year on year and understands Rangers. Measuring that against most of the other candidates he comes high on the list if not top. It might not be the most exciting name but I think it's exactly what we need.
