This complaint seems VERY empty to me. Not only do they have invested in young talent at affordable prices, they have some cap room available to work with going forward.
In all, NO has nothing to complain about. In fact, most would have agreed that NO had a very good team coming into this year.
So seriously, not sure what this dude is complaining about at this stage of his career about failing to add a star around him... particularly when you consider they traded for an all-star PG, currently injured as he may be.
Edit: My post seems like it's completely misplaced. Only read the OPs post, so thought AD was complaining about the talent, yet I don't see anything like that in the link provided.
