Brett goes too far

We’ve seen it a dozen times.

Some old boxer retires … and unretires ... a few times.

He can’t step away from the ring, even though he’s over the hill like yesterday’s sunset.

It’s pathetic, but then boxing isn’t much of a “sport,” so I guess it doesn’t matter much.

Pro football is different. And Brett Favre is really different.

Sadly, the great quarterback is acting like a lousy boxer.

A few months after the typically tear-filled press conference in which he swore up and down that he was leaving the game because he had absolutely nothing left to give … well, he wants to come back.

If the Packers would just give him his No. 4 jersey and point him toward the field, I guess we could chuckle at another Huck Finn moment from Favre and wait for the new season.

But Green Bay is balking. The owners used their No. 1 pick on a quarterback three years ago — Aaron Rodgers. They’re tired of paying him big bucks to hold a clipboard on the sidelines.

Besides, Favre has gone through this will-he-or-won’t-he Hamlet act for a few seasons now. This time, it looked like he meant it … for a few months.

So now they don’t want to take him back, and Favre is asking to be released so he can sign with another team.

Sacrilege. That’s like putting Babe Ruth in a Red Sox uniform. … OK, he did wear Beantown duds earlier in his career, but you know what I mean.

Favre runs a huge risk of tarnishing his legacy and embarrassing himself on the field.

Maybe the really sad thing is that this man-child doesn’t have anything else to do with his life.
