Let’s get Physical … with an “F”!

The San Fransisco 49ers recently took the interim off now head coach Mike Singletary, but apparently the new contract didn’t come with a spelling 101 class.
In a recent interview with the media, when asked about his defenses tendency to hold back on plays, Singletary spoke about his philosophy on defense saying that his teams was going to be, “physical with an F.”
Here’s a real word with an F: What the fuck? Did he really think physical was spelled with an ‘F’? He couldn’t have right? Or is physical spelled with an ‘F’ because of what he wants his defense to do to the offense they’re playing against?

I think what he was getting at was “physical with an F” being “fucking physical”… please god let it be so…
