I asked the same question when I met their Director of Marketing in the off-season. The answer he gave me: Johnny Morris is a very loyal guy. He never likes leaving anyone completely out. He had a long, successful relationship with RCR, so he continues to support them (albeit much smaller level). He had a great relationship with Tony, so he continues to support SHR. He had a great relationship with MTJ, so that's why their "primary" funding is now with the 78. One day, they might move on, and still leave behind a few paint schemes for the 78 guys. That's "just the way Johnny is."
