Last Season, Crosby+Karlsson had 93+101 for 194, and McDavid+Bouchard had 153+40 for 193.
However, Bouchard's playoff performance was very scary and if he can get anywhere near that performance, he should be able to increase his scoring rate significantly. Meanwhile, both Crosby and Karlsson are aging, and it's unsure how well Karlsson will mesh in with a new club.
