On the sheer numbers, I think that there are any number of teams that hit better than the current BJ's, incl the 80's BJ's, the WS BJ's and the BJ's in the late 90's and early 2000's. The difference is that the current BJ's do it while offence as a whole has dried up around the league and are dominant relative to the other teams they face.
There are probably 10 or so guys this year in the AL who will hit 100 rbi's. That's a far smaller number than usual. 3 of those guys are going to be Blue Jays - EE, JB and JD!
