Sid shouldn't be even in top3.
He had only 12 points in 15 games w/o Malkin that season=0.8 PPG (and
1.47 with Malkin)
If voters gave him Hart it would be disaster for their creditability.
Malkin missed 15 games that year; here is Sid production w/o him:

Entire Sid's 2009/10 season projection without Malkin:
16 G / 66 P / -27
That 3rd place by Hart votes is extremely generous. He is a Canadian golden boy.
Entire Sid's 2009/10 season projection with healthy Malkin:
60 G / 120 P / +19
1.8 times more points and 3.8 times more goals.
I remember zillion posts from his fans, that Sid could easily score more goals if he wanted to.
