With Aldon Smith agreeing to a contract, he is the fourth former first-round pick the Cowboys have added in free agency so far, joining Gerald McCoy (2010), Dontari Poe (2012)and Ha Ha Clinton-Dix (2014). Smith was the seventh pick in the 2011 draft. The Cowboys are following philosophy they have held over years in bringing in players who at one time teams liked greatly. Smith is a risk but likely mitigated by the financial commitment.
