Those farms certainly had some low points, but under Theo and Ben, there were some rock solid ones, too.
The year you speak of, 2010, was not the worst.
#1 Kelly was highly regarded and was part of that AGon trade with #3 Rizzo.
Kalish was #3, Iggy #4, Doubront #5, Reddick 8, Workman 19 and Westmoreland- a very sad case. After that trade, our farm hit one of its lowest point in the last 2 decades, but soon Bogey and others beefed it back up.
