Here are several examples of who vs. whom that I've found recently:
Who is it: He's a believer, and so are many of the players, whom have taken on a
different mentality, an altered approach, according to tailback Reggie Bush.
M
Let's change the middle of that to "...the players, who have taken..."
Yes, there are times to use whom, but who should get its due, too.
Found online: After all, whom are the Dolphins going to get to replace Sparano on an interim basis?
That's right. Who would work better here.
Another problem: Therefore, this notion that Rivera can hire someone who might be able
to develop an offense that can highlight the skill set of Jimmy
Clausen, or whomever is the quarterback, is a little farfetched.
Yes, whomever should be whoever.
Whoever is next will work fine.
More later.
