LAKE FOREST, Ill. -- Here’s a look at the first-half impact of the Chicago Bears' 2017 draft class:

Mitchell Trubisky, QB, first round: Trubisky took over for former starter Mike Glennon in Week 5. The second overall pick has mediocre statistics over four starts (38-of-80 for 512 yards, two touchdowns and two interceptions), but he’s also made several impact plays. Trubisky is still learning on the job, but he’s got potential. Grade: Average

Adam Shaheen, TE, second round: Shaheen has only one catch -- the reception happened to be a touchdown -- in eight games. The Bears billed Shaheen as a playmaker coming out of tiny Division II Ashland University, but the 6-foot-6 tight end has so far been a nonfactor. Shaheen’s role is likely to increase with Zach Miller out for the year. Grade: Below average

Eddie Jackson, S, fourth round: Jackson became the only player in NFL history to have two 75-plus-yard defensive scores in the same game when he torched the Carolina Panthers in Week 7. Jackson won NFC Defensive Player of the Week honors for the performance. Grade: Above average

Tarik Cohen, RB, fourth round: The Bears have used Cohen in almost every possible way: running back, receiver, quarterback, punt returner and kickoff returner. Cohen hasn’t touched the ball much in recent weeks, but he’s still had an excellent first half with 724 total yards from scrimmage, one touchdown run, one touchdown catch and a touchdown pass. Grade: Above average

Jordan Morgan, OL, fifth round: Morgan has been on injured reserve the entire year. Even before he got hurt, Morgan didn’t stand out much in training camp or the preseason. Grade: Incomplete
