You'll perhaps forgive me for not caring about your inability to find new information, and your apparent lack of perspective on just how much data of the sort you were seeking is actually out there about any pre-war player. Apparently, I found more on Jackson's physicality nine years ago than you were able to last year. Oh well. Nobody's calling him some kind of wunderkind of a glue guy, but by the standards we've got for information from the pre-war era, there is enough to establish that he was a big, strong, aggressive, physical player. I don't think anyone's ever claimed he had more "intangibles" than that.
We can also get into the glaring difference between Busher's voting record and that of another star LW from his era (who was actually a slightly better scorer) when he gets drafted. The difference between them certainly wasn't scoring, so why did the voters like Busher so much more? I guess we'll cross that bridge when we come to it.
You raise your elbows if you like, my man, but I hope you're ready for the same. "I couldn't find anything new" isn't much of an argument. Among other things, it fails the "falsifiability" criteria for real, empirical research, as there's no way for others to judge the significance of your lack of additional material.
