Why limit a good and fun concept to just hockey when I have enough signed baseball cards to seriously consider adding a Montréal Expos Numbers Project to all my hockey ones (my Habs Numbers Project, my Oilers Numbers Project my Sens Numbers Project, my Canucks Numbers Project, and my Nordiques Numbers Project).
It'll be harder to finalize because baseball has more players in uniform (factoring in spring training and the 40-man roster after the trade deadline), but I start with the advantage that the team no longer exists, and no new number will be worn.
The first Canadian (and first non-U.S.) team to join Major League Baseball (in 1969), the team had its two best seasons when strikes disrupted play: the 1981 division win, and the magical 1994 season where they were leading the majors with a month left of play when the playoffs were cancelled as players walked out, which rang the beginning of the end for the team, who started its first official fire sale.
There'd been prior instances of the team trading highly-paid veterans for youth when they were being priced out of the team's budget (Gary Carter), but post-1994, it actually became official team policy to always trade players when they hit their prime and were about to earn serious dough. From the first wave (Delino DeShields, Marquis Grissom, Larry Walker, John Wetteland) to the second (Pedro Martinez, Jose Vidro, Vladimir Guerrero) to seasons where it was a single player to when the Evil Twins came from New York with empty promises and ran the team to the ground so they could profit from its sale and trade up, to the Florida Marlins.
