In Detroit, take a look at his injury history, and try not to cry yourself to sleep.

It’s convenient that we’re looking at a one-game sample, but remember to be realistic about his season-long value. Sizemore’s still a risk.

2. The Reds lineup could be in trouble.

Speaking of single-game samples, it’s probably a good idea – no, it is a good idea – to not have knee-jerk reactions after 0.62% of the season has been played. But I’m going to do that anyway, because it makes for a more entertaining article.

The Reds lineup could be in trouble. Yes, I’m fully aware that they faced one of the best pitchers in the game yesterday. And yes, I know taking that performance and making a sweeping generalization probably isn’t the smartest thing to do, especially considering Reds fans will be reading this and they'll let me hear it. But this is something I wrote about in my injury history, hamstring issues are common for the Blue Jays shortstop. In fact, with the Mets, Reyes spent time on the DL with hamstring issues four different times. Stretch them out a little, bro.

We’ll see how severe the injury is now, but anytime you have Reyes stock, you should be prepared with a fill-in.

10. People are going to overreact.

Perhaps you’ve read this article and are now saying, “But you’ve overreacted with at least half of these statements!” While it may come off that way, my goal is to just give a glimpse of what’s potentially to come based on more than just Opening Day.

The Rockies aren’t going to go 0-162, being outscored 1,620 to 162. Cliff Lee isn’t going to finish the season with an ERA above 14.00. Billy Hamilton won’t strikeout every time he’s up to bat. And Grady Sizemore isn’t going to bat .500.

You have to analyze any small sample – even through an entire month – with a grain of salt. We can all still learn things from a game or two, but don’t let that overshadow the massive amounts of research you did before the season started. Making knee-jerk moves in fantasy baseball, or getting into bar arguments based on one game’s worth of statistics isn’t a smart idea. Trust me.
