It's more than just lagging behind in TD compared to the competitors. It's a multitude of a truck load of bad decisions made over the last decade. With the most optimistic outcome of current efforts in TD, it will take at least two years to see some good results. Please evaluate if you have other options, if you must, jump in and focus on learning the systems, processes, and people's skill - nothing to loose there. You will be fine.
