Boras was one of six coaches, including offensive coordinator Ron Turner, who was let go after the Bears concluded a 7-9 season, their third straight without a playoff berth.
"Rob Boras is a great coach, and I'll be interested to see why they let him go," Clark said on "The Afternoon Saloon" on ESPN 1000. "That will be one of the questions I will ask when I get back up that way to Halas Hall.
"Hopefully when I do ask the question, they say, 'This is the reason why we let him go.' Whether I like it or not, he's gone, and I have to be prepared to have another coach next year."
Clark said the reason he didn't question losing his starting spot to Greg Olsen before the season was out of deference to Boras.
"I think I just owe it to him to let people know what type of coach he was," Clark said. "He never stepped out in the media and said anything. He wasn't a self promoter. He was a quiet guy who came in early in the morning and got his work done and left late at night.
"This is how much respect I had for the guy: When they said I wasn't the starter anymore, and I didn't have a chance to fight for my position, you didn't hear me say a negative word about it. Although I may not have agreed with it and thought I should have had a chance to fight for my position, I didn't say anything because I didn't think my coach deserved to have to go through what would come with everything because of what I might feel or what I might say. So out of respect for him is one of the main reasons I didn't say a lot about not being able to fight for my position. Saying that, I still understand why they made Greg the starting tight end, because he is a great tight end. That's the kind of respect I have for the guy."
Clark didn't think the coaches who were fired were surprised.
"I don't think any of the offensive coaches were caught off guard," Clark said. "There was speculation during the last half of the season that the offensive coordinator for sure would be gone, and with the offensive coordinator being gone, most of the offensive coaches would have to find new jobs, too.
"So I don't think it was a surprise to him. It was more of a surprise to me. I thought they knew what kind of coach they had in Rob Boras, and I thought they would go the extra mile with at least letting him interview for the coaching position once we got a new offensive coordinator."
