made this point all day.
he had a guy in on ST that wasn't his regular starter, dove for a fair catch punt in the 1st half, then had one bounce off his leg.
on the other side of the ball, after the bounce off on Williams, Coughlin switches to Aaron Ross and tells him to catch and secure the ball get your yards and go down before contact.
in OT, WIlliams gets stripped on a pretty simple play.
If Harbaugh wanted him to stay aggressive on his returns, then he wasn't paying attention to the conditions or situation, or he didn't trust is offense, or both.
bottom line, our coach saw the danger and adjusted, there's gambled and lost.
Don't blame the player for that, blame the coach. he had enough signs on the field already that he should have said something to him (assuming he didn't obviously).
