Spend enough time in a Major League Baseball front office, and you get used to having to make decisions before you have access to everything you'd like to know.
There may be a player you're interested in, but you haven't seen enough of him yet to feel certain about what he'll become. The data may tell you one thing, while a scout who has watched him for months might come away with a completely different impression. You can keep gathering information, but eventually you have to decide — and sometimes the opportunity won't wait.
