Dave Winfield, Paul Molitor, Jack Morris, Dave Stewart, Roger Clemens and probably a few other guys I'm forgetting. You could fill out an all-star team with who the Jays recruited as free agents in the early to mid-90's with a competitive team, an adept GM in Gillick and a still somewhat sober cheerleader/ambassador in Beeston. They haven't done that lately because...Ricciardi, Godfrey, Ash and drunk Beeston.
So f*** off with your loser self-hating Canadian mentality. Especially you Saskatchewan people who are utterly disconnected from Toronto. As far as frequent travel, come on man, these are ballplayers flying charter. Do you really think carrying the extra passport is that much of a burden? Toronto is pretty conveniently located in between all the major baseball cities too. Can't be that much worse travel wise than Minnesota, Seattle or Tampa.
Taxes/uprooting family, yeah I can see how that might be an issue. Especially for redneck type of players. But there has to be at least a few players, especially black or latino ones that look at Trump and the general political climate there and look at our situation up here and see a benign pretty boy (yes Trudeau sucks, but they don't know that), health care, not a mass shooting every two days that their kids have to wear bulletproof vests to their snobby private school and say "hey, maybe Canada is not so bad". It's two sides to every story, not just "awww wah wah wah Canada is a cold, s*****, tax-filled nation".
