Shefter is "hearing rumblings". That isn't a surprise -- everyone and their brother out there is trying to drum up interest and rumors, so the "rumblings" are out there.
In the actual video though, Schefter wasn't saying I've heard rumblings that Trubisky is in contention for the number 1 pick or something similar.
It was more my sources are telling me, he will be the pick.
Which represents a pretty significant shift in rhetoric, imo.
