Honestly, it's kind of shocking how much worse his defensive acquisitions have been compared to Sean.
Who are our best defenders currently on the roster?
Poyer
Hyde
Tre
Milano
Jerry
Do you notice something? 4 of those players were acquired by McD without the McBeane. Jerry was obviously already here.
Compare it to the list of hacks that Beane has acquired. I'd type out all the bums and disappointments but it'd take too long.
