Forgetting the topic of speed for a second, the phrase "you cannot underestimate" always seems confusing to me. Presumably you're talking about something you value highly when you start a sentence off with those three words. However, if you are saying you cannot underestimate something, you are essentially saying it is not possible to place a value on something that is lower than the actual value, or, this thing is so lacking in value that it is impossible to arbitrarily name a value that would be lower than its actual value. Or, in this case, speed is so worthless, you can't possibly come up with a value, however stated, that is lower than the actual value of speed. Although, if you take is as a command, as in "YOU, yeah YOU, you are not allowed to underestimate the value of speed." Well, besides being a little harsh, this pretty much guarantees the person will be forced to overvalue speed, or whatever the object/concept is, because nobody can assume you will be perfect when assessing value. So, in other words, the value of speed is going to be overestimated, because it's either impossible to underestimate it, or you are not allowed to underestimate it. It's like saying "I couldn't care less" when if fact you could very easily care less. Anyway, it's been one game. You can't use one game to show us anything about how the offense will be different from year's past. Personally I'd love all Cubs players to have blazing speed as one of their many abilities, along with elite vision, hand eye coordination, balance, strength, quickness, intelligence, decision making ability, instincts, spunk, grit, confidence, clutchiness, intangibility, chemical capability, courtesy and generosity (to the fans and need, not opposing teams). But I don't think it's possible to find such a player, or group of players. So I'd just like to see them assemble the most productive group of players possible with a mixture of several traits.
