I do not share this. With this perspective, you reduce your possibilities. You need to monitor other divisions as well, look..
1. Current Division scenario. You need to beat NY and TB and who knows? TOR could be a surprise. Today, I see NY above us and TB maybe is at the same level.
2. Current WC scenario. The other oportunity would be the wild card. You will likely compete with LAA, TB and probably another unknown team. (on paper, of course)
I would base my strategy in both, 1. try to win the division (unlikely today) and as plan B win the WC (likely). Once in the PO, you never know.
