As @ashbury said, just because the team is taking advantage of the weak schedule, that doesn't mean that they're for real. I'm not quite as pessimistic as he is, but I'm also a realist. I think "real" is relative. Given the division, they should be favored to win it. I even upped my expected win total on the season largely because of how bad the division is. But that doesn't make them a legitimate and real contender.
I said before the season that this team will go as far as the young guys will take it. The young pitchers have stepped up so far, but they've shown chinks in the armor too. The young bats have done a decent job overall, but still need plenty of work as exhibited by last night. The Kershaw's and Verlander's of the baseball world are what they'll be facing in the playoffs almost every day.
