This appears to be an oxymoron...if he's a good analyst, then he is inherently smart. Gammons has so much credibility that he doesn't need to "make himself look smart."
Gammo is the most intelligent baseball analyst out there, IMO. Even though he is slightly biased to the Sox (he did write for the globe for years), he knows about everything that is happening and baseball. Lately, he's been opining about politics and music, which I don't particularly care for.
I was at the game Sunday night, in dead center field (section 34). DLowe's sinker WAS nasty. Unfortunately, his slider was off. Everytime he got ahead in the count, he'd go to his slider, which would miss away and increase his pitch count. Note that Lowe only let up 2 runs, yet had a pitch count of ~100 through 6 innings. His sinker was definitely ON Sunday night...it was his slider that was OFF.
