		John Clayton's worst free-agent signings of all time
	1	Nate Odomes, CB, Seahawks (1994) Clayton's take: The Seahawks brought him over after years of Pro Bowl performances with the Buffalo Bills but barely got him on the field. An offseason charity basketball game might have been the final straw in blowing out a knee, but the knee was ready to explode anyway from playing all those extra playoff games during the Bills' Super Bowl streak. For the Seahawks, they paid the money but didn't fix the cornerback position.
	2	Tony Casillas, DT, Chiefs (1991) Clayton's take: The Chiefs hoped that he would bring the dominance he displayed with the Atlanta Falcons. After showing a lot of heart with the Falcons, Casillas' heart, soul and mind wasn't into playing. He took the signing bonus, quit the Chiefs and eventually was forced to pay back his money.
	3	Gabe Wilkins, DE, 49ers (1998) Clayton's take: The 49ers thought they were getting a $4 million-a-year defensive lineman after watching this raw talent show amazing athletic skills in Green Bay. Wilkins came to the 49ers with a knee problem that only got worse. Wilkins played 24 games and the 49ers had to take a huge cap hit after letting him go after two seasons.
	4t	Alvin Harper, WR, Buccaneers (1995) Clayton's take: This is a duel entry because the Buccaneers suffered the same fate trying to get a speed receiver at split end. Harper couldn't recapture his deep sideline magic he showed in Dallas opposite Michael Irvin. ...
	4t	Bert Emanuel, WR, Buccaneers (1998) Clayton's take: ... Emanuel, who was his $4 million-a-year replacement, was always hurt. It cost Tampa Bay too many Bucs fixing this spot.
	5	Dwayne White, G, Rams (1995) Clayton's take: The Rams thought they were getting a dominating run blocker. With the Jets, White was known as the Road Grader. With the Rams, he was forced to hit the road because he was too fat and could only play a couple of games.
