The below from Kevin Goldstein at BP. I advocated taking Lincecum this year based on everything I had seen. Certainly you can't call any pitching a sure thing, but wow.
Tim Lincecum, rhp, San Jose Giants
In the age of ubiquitous communication, information can come from anybody, anywhere, and at any time. Last night while looking at boxscores from the day's games, an IM window popped up from somebody who sees as much California League action as anyone, who was watching San Jose take on Visalia. Four simple words: "Tim Lincecum is sick." Sitting at 95-96 mph and touching 98 on numerous occasions, Lincecum allowed one hit over 5.2 shutout innings, allowing one hit, walking two and striking out 11. In 26.2 innings as a pro, Lincecum has 49 strikeouts and has limited opposing batters to a .138 average. At 5-foot-11 and 160 pounds, Lincecum's ability to do what he does is often referred to as "freakish." One of my few hobbies outside of baseball is reading a lot and collecting a little concerning sideshows of the early 20th century, in particular, human oddities. In that world, there were two types of performers--the real deal, and "grifts," or fakes--and part of the interest in attending such shows was the debate over which attractions were the genuine article. Those who thought Lincecum was a grift dropped him to the 10th overall pick... and they were wrong.
