Has Carimi really dropped to second-round territory? I haven't paid any attention to pre-draft stuff, but I remember hearing he was a sure-fire first rounder early in the college season.
He's 30-17 as a starter in the NFL and he was 30-2 in college. He wins more than he loses.
"Disruptions to team chemistry" are overrated. The Jets are in the playoffs.
I can tell you this -- "hanged" in regards to suicides, lynchings, etc., has been around for many, many years. A search on the New York Times website will show results back to mid-1800s of men "hanged."
A simple way to find out is to substitute "he" or "him." If it fits as "he," it's who. If it's "him," it's whom.
So, by that rule, your example would be "whom."
It doesn't always work, but usually.
