Harbaugh needs to show some tact. This is not the first week he has called out other teams/officiating/coaches (win or lose), publicly. I have no doubt that other coaches get upset about calls, and then bring them to the league office. Harbaugh is trying to gain a a competitive edge by taking this public (more media/fans in officials/leagues faces). He could easily take the high road when giving responses.
Lots of whiny 49ers fans too (obviously not new). As if the most penalized team in the league is in the favor of the refs? Honestly, every team, in every game, gets away with a lot of penalties (of course they are going to keep doing it if it doesn't get called). There were plenty of non-calls on the niners side of the ball as well, OPI/PI/Holding/Late hits. Pete is not publicly calling that out.
We play some physical ball, and some sissy nanny WRs can not handle it.
Harbaugh is like that soccer dad that constantly is shouting at the 15 year old official about how the other team is stopping his kid from walking it into the goal untouched.
