Mo Not the Best of All Time?

From the Baltimore Suns Four Corners feature comes reason number 8,897 why newspapers are dying:

Four Corners: Who is baseball's greatest closer of all time? Dylan Hernandez Los Angeles Times Eric Gagne. OK, so the Mitchell Report taught us that his performance might have been enhanced. So what? The use of performance-enhancing drugs is a natural byproduct of American culture, but that's a subject for another day. Let's take a simpler approach to this issue. There are only two somewhat objective measures we can use to compare athletes from different eras: relative dominance and longevity. Gagne wins hands-down in the first category. No one was as dominant as he was during his streak of 84 consecutive converted saves. Mariano Rivera wins in the latter category. So who is the best? Personally, I tend to favor athletes who soared to the highest of heights over those who sustained brilliance over long periods of time. dhernandez3@tribune.com

Uh... what? So, Mr. Hernandez believes that a player with a short peak and surrounding failure is better than consistent dominance over a long period of time. I haven't read much of Hernandez's work at the LA Times, but I am assuming that his career is following more the path of Eric Gagne than Mariano Rivera.
