Rookie Terrance Williams made some mistakes for the Cowboys in 2013.

He ran two wrong routes leading to Tony Romo interceptions in victories against the New York Giants and Minnesota Vikings. There was Williams fumbling the opening kickoff against the Oakland Raiders.

Williams also had a three-game stretch when compiled just four catches for 64 yards.

But there is so much more to Williams' season, and it's time for him to take over a starting role at wide receiver. The Cowboys are expected to part ways with Miles Austin to save $5.5 million against the salary cap.

That would mean Williams would start alongside Dez Bryant in an offense expected to increase the number of passes thrown with new play-caller Scott Linehan.

Williams was a big-play threat for Romo last season with 12 catches of 20 or more yards. Overall, Williams had 44 catches for 736 yards and five touchdowns, with three of those scores going for at least 20 yards.

Williams has good speed, and improved his route running as the season progressed. Becoming reliable is the key for Williams in his development. Bryant dealt with similar questions after his rookie season, and as you saw in 2013 he produced his first Pro Bowl season.
