Trevor Penning was the only addition the LA Chargers made at the trade deadline, but trading for him wasn't the biggest gamble the Bolts took. Trading for Penning was the equivalent of betting a nickel at a $5 blackjack table; Los Angeles' biggest gamble was more like staying with a 12 against a dealer's face card.
The Chargers opted not to add any running back help at the deadline, instead putting faith in second-year running back Kimani Vidal. Vidal has had an up-and-down tenure, and with Omarion Hampton still on the shelf, it seemed inevitable that the Chargers would add running back help.
