Wilson is expected to be Chicago's No. 3 receiver this year behind Marshall and Alshon Jeffery, and Marshall said in an interview with CBSSports.com that Wilson has worked hard this offseason. The trio of wide receivers have trained together in South Florida to get ready for this year.
"I really want to talk about Marquess Wilson," Marshall said. "He came down and trained with us the whole offseason. We're really looking for him to do some big things. This guy, he's probably the steal of the draft last year. I'm going to say that. He came in, he put in the work, he looks like a body builder. Fast, strong, explosive. I'm looking forward to seeing him in OTAs."
Wilson, who is 6-foot-4, 184 pounds, was drafted in the seventh round out of Washington State last year. He only had two catches for 13 yards as a rookie, but he will now replace the departed Earl Bennett in three-receiver sets.
Last year, Marshall dealt with minor hip surgery in the offseason, but he said thus far he's in great shape and ready to go.
"The offseason is amazing," Marshall said in an interview with CBSSports.com. "It seems like every other year I get a healthy one. Last year I had surgery and really couldn't train. This one, it's a successful one so far because I'm healthy. Next year should be a big year for me. I'm looking forward to it being my best year ever."
Marshall, 30, is coming off a solid year in his first campain for new coach Marc Trestman. He had 100 catches for 1,295 yards and a career-high 12 touchdowns.
This is a contract year for Marshall, who is scheduled to make $9.1 million in 2014. He told a Chicago radio station in March he's going to force the Bears "to sign me after next year," and he's not worried about getting paid.
"Everybody wants to get a new check," Marshall said. "That will happen when it happens. ... If you go out and play then everything else is slotted. You have to perform. You have to keep the product on the field good."
Mannelly said he'll probably decide next month whether to come back. The Bears are hoping he does, the report said.
