Thought implications of Key saying he was pleased with Reed as the #2 center are interesting:
First, it seems to imply Key already views Ionata as being the clear #1 center. This, combined with his praise for Ionata implies that perhaps the biggest question mark on the OL is resolving.
Second, the fact that he is pleased with Reed as a #2 C implies not only do we have a guy who has won (or is winning) the position, but that we also are developing viable depth.
We may or may not be strong at center but it sounds like Key likes what's going on there.
