Horvat is in his 4th season in the NHL.
Ok ok ok, Again mind you he had 52 last year as a 22 year old.
Are you saying that if he was on a contending team he wouldn't get as many points? Your logic is insane! So what Kesler had 59 points in his 5th season? Guess what? Horvat had a better rookie season, better 2nd year, better 3rd year, and is having a much better 4th season than Kesler, as you said, on pace for 56 points, playing 1 season less.
Now notice Kesler's jump from 08 to 09. 08 he had a declining Naslund, Morrison, Taylor freaking Pyatt as his linemate, and 26 year old Sedins with 70+ points. 09 he had Demitra, Burrows, Sundin and 27 year old Sedins with their first 80+ season. Notice 08 bad team, Kesler only had 37 points as our 2nd line center. 09, we have a contending team, and oh, he has 59 points, with quality players around him AND 2, not 1, 2 80+ point players on our team!
