So when his average fastball has declined drastically and has shown a trend in it declining, his SO/9 has been declining, and he's been very hittable since 2009, I'm not supposed to take that as a downward trend?
Why do you consider Rosenthal a "reliever with middling talent"? How is a pitcher who has averaged just .3 mph less on his average fastball than Chapman considered a reliever with middling talent? Have you not even watch him pitch or understand why he was rated as high as he was in the prospect rankings (39th according to baseball america)? Good lord dude, you make Rosenthal look as if he's a Kyle McClellan type pitcher.
