Huge by canuckian ***** measuring standards. Which means it's about 2 1/2 inches tall.
A lot. I'll use my Hamilton team as an example. Not much changed from last season except for D. I'm using a very good 1B/quite pedestrian LF in LF and a declining skills old guy in RF. Both played those positions(LF was part-time) last year and managed to hold their own. Both are playing like blind men with iron gloves this year. My almost identical pitching staff went from being almost a half run better than league average to being more than a half run worse than league average. Of course, random results and changing enviroments play a part but that's a big change.
