Only 20 draft picks from the 2017 NFL Draft remain unsigned as training camps approach.

Among those unsigned are eight first-rounders, including second overall pick Mitchell Trubisky and No. 3 selection Solomon Thomas.

The Los Angeles Rams have five unsigned rookies, all of which were selected in the fourth round or later.

Jordan Howard is motivated to prove his rookie season wasn't a fluke after he finished second to Ezekiel Elliott in rushing with 1,313 yards.

Howard didn't play Week 1 and the Chicago Bears didn't start him until Week 4.

"I feel like some people might feel like I might have been just a one-year wonder," he told the Chicago Sun-Times. "That's motivation to keep coming out here and working and improving my game."

Howard wants to catch more passes after hauling in 29 receptions in 2016.
