Clayton showed flashes, but was mostly a disappointment in Baltimore. Despite being a former first-round pick, Clayton never developed enough consistency to be a great NFL receiver. There were times when he would record more than 100 yards receiving and then completely disappear the next two or three games, which was puzzling.
The bad news is Baltimore didn't get much value for Clayton. But adding Houshmandzadeh to the roster and trading Clayton is a significant upgrade in my book.
