Real, Joey.
Regarding Taveras, I'm as baffled as you with respect to the complaints about his slugging. Taveras is a legit threat to turn every single into a double or triple with his base-stealing abilities. Commentators like Sickel don't seem to understand that a CF like Carlos Beltran is the exception, not the rule. Also, I find the pejorative reference to Juan Pierre ("at best") highly amusing.
I will agree, however, that Taveras needs to work on his K/BB and OBP to maximize his leadoff performance.
Regarding players like Conrad vs. players like Einertson, your point is also well-taken. The funniest part is, the commentators at BA and other rags make the same mistakes every season, by over-hyping youngsters who put up big numbers at lower levelas and under-rating older players who perform well at higher levels.
A great example of this phenomenon is the Lexington Legends OF trio of 2001. Topolski, Hill, and Rosamond all put up tremendous numbers at Low-A Lexington that season. Subsequently, the commentators and scouts and what-not went wild over them. Unfortunately for those guys and the Astros, however, none of the three has ever been able to sustain that kind of success at AA or higher. In '04, Topolski was a back-up in Round Rock, Hill bounced between Round Rock and New Orleans (without much success at either), and Rosamond (a former 1st Rounder) was released outright, first by Houston and later by the Rockies, too. I'm not knocking any of these guys personally, as I know at least a couple of them to be really good guys. However, the point remains that performance at lower levels does not necessarily project to performamce at higher levels or the Majors.
Conversely, and perversely, the Astros seem unwilling to afford opportunities to guys who HAVE performed well at higher levels, e.g., Burke, Huffman, Conrad, Self, Whiteman, etc. Perhaps they rely too much on the opinions of commentators like Sickel and the BA bunch, or the "projections" of scouts, in this respect.
