Let's just say Dempster would have nowhere close to 9 wins and wouldn't sniff the top 5 in ERA and WHIP, Ted Lilly would have allowed 25+ HRs, Jason Marquis would have an ERA approaching 7.00 and Kerry Wood's job would have been taken away six weeks ago. Other than that they'd be fine, a very solid fourth place team.
Cubs would win 95 games in AL and will win 92 or so in NL
