The fact Claiborne never played more than 11 games in a season after his rookie season. The next 4 years he played 32 games or 8 per season. Plus he had only one good season. But he can be really good.
I certainly would have. Pretty happy with him at 7.5 he is a bargain. He played 12 games on average the last 5 season which is not great but ok. Plus he is consistent you know what you are getting solid, above average to good CB play. Thats why I choose him over Claiborne
