Sigh. Lavarnway was never named Red Sox defensive player of the year. He was the Red Sox minor league co-offensive player of the year in 2010 (with Anthony Rizzo) when he hit 22 HR and drove in 102 runs in 462 AB. FWIW, Baseball America named him best power prospect in the International League the following season.
I'm trying to be nice here, but your contributions to this discussion have been consistently incorrect and poorly researched. First you said, "Far older than all those guys too, though" when I said Dalbec got to 30 HR in fewer PA than Conigliaro, Dropo, and Williams. That was false, and something you could have checked with a 60 second Google search, as Dropo was a year older than Dalbec when he reached 30 HR.
Next, after I said I thought Dalbec was a solid defensive 3rd baseman, you replied, "I don't think many people agree with your assessment of Dalbec being a decent 3b." I responded that the Red Sox named him defensive player of the year in 2018, which more than suggests other professional evaluators also were high on his defense, and your response is above. In it, you not only incorrectly say Lavarnway was once DPOY, but also are apparently claiming your defensive assessment skills are superior to the Red Sox scouts and front office employees. Eddie Romero and Gus Quattelbaum will be thrilled, I'm sure. It was a bizarre response to double down after being (nicely) shown your comment about my view on BD's defense having no backup was incorrect - the Red Sox minor league guys also think he's a decent defensive 3rd baseman.
I would strongly suggest you take more time before posting. Consistently having easy to research false info in your posts removes all credibility from your opinions.
Back on topic, you clearly think Dalbec is a poor defensive 3rd baseman, to the point where you degrade the Red Sox opinion on this. I'm assuming you have seen him play 3rd multiple times, and have extensive experience as a pro baseball defensive evaluator. Please give us your views of Dalbec at 3rd, including what he does well, where his weaknesses are, etc.
