The money line to come out of the report is going to be "over 100 contacts with Russia....[and Wikileaks]". Throwing text messages with Wikileaks in there probably increased the hit count significantly. I didn't bother to look if details were provided if those were mutual connections, or unreturned and unsolicited attempts from Russia.
Otherwise, I'm not sure that's a large number of contacts. A Presidential campaign is going to have a mix of long-time political insiders, maybe with a mix of people from global corporations. I'd expect a fair number of perfectly legitimate contacts with Russia, China, Middle East, etc...I guarantee Hillary, Podesta and Abedin probably rack-up a pretty impressive hit count there themselves.
