PHILADELPHIA (CBS) -- Chip Kelly and Angelo Cataldi are two of the most polarizing sports figures in Philadelphia. But this is something even their biggest haters can't criticize.

On Thursday -- during what has become Cataldi's weekly tradition of delivering pies to the Eagles -- the 25-year sports radio host on SportsRadio 94WIP and the third-year Eagles' head coach signed checks to donate to charity.

Kelly vowed to give $1,000 per pie to the Greater Philadelphia Coalition Against Hunger (donate here) and Cataldi chipped in $1,000 of his own, for a grand total of $4,000.

The pie-delivery tradition started and ended (we thought) in 2013, when the Eagles won six of their final seven games thanks to Cataldi's pies. But a few weeks ago, amid three straight Eagles' losses, Kelly requested the pies again for good luck. Cataldi delivered and the Eagles are undefeated, 2-0, with the pies this season.
