When talking with Iowa, they did indicate this as well. However, they did indicate that part of the issue is the ability for candidates to relocate. If you are willing to relocate and take a non TT position for a year or two, you can connect with a TT position.
Overall, TT positions are shrinking as the academic world is in adjustment. Recent graduates at the Seminary that I attended, have taken three to five years on average to get a TT position. The individuals that did not take that long, specialized in a field in which they are the minority.
So overall, it seems that a lot of institutions are placing less and less in a short time span.
