St. Louis/L.A. Rams – Courtland Finnegan
If the Rams had the best version of Finnegan, he wouldn’t be on this list. But his level dropped to a different stratosphere when he joined as a free agent in 2012. The former Titans star became one of the league’s top defensive backs. Wear and tear began to take their toll on his body but the Rams ignored the warning signs.

They awarded him a massive $50 million contract because they believed he would be a difference-maker. In the end, he was but not in the direction that they hoped. Finnegan barely survived for two seasons in Missouri before they released him. It was a remarkable fall from grace but sometimes this happens in the NFL (via SBNation).
