Maddux, Pedro, and Glavine were not hard hitters (especially Maddux). But Clemens and Johnson were (Johnson especially with that sick slider).
Also on Maddux, he was consistently great.
The other five are fairly young, so we'll have to wait and see if they can sustain this. Being out east, the only one I sort of know is Lester. Is Felix that good, or is it that he's on a crappy team? I hear him mentioned in spurts. Greinke had a good year last year. Lincecum I will grant you looks like the real deal.
But what do you mean exactly by "scare you"? Lincecum (the best of the second 5) isn't exactly overpowering either.
