Agree. I don't see every game, but it seems to me when Eck's in the booth, any conversation about himself or his career centers around some mistake he made (a "bomb" he gave up or some time when he made a boneheaded play like forgetting to cover first; as I recall, his words on that were "we've all done it"). "Yuck" may not have been the most artful of adjectives to use, but would "ugh" have made things any better? He's not Vin Scully.
Eck says it like he sees it without a whole lot of bias. If a Sox player makes a great play, he says it. If an opposing player makes a great play, he says it. Ditto the bad plays. Problem is, the feedback on the former somehow never gets back to players; they only hear the negative.
