Wondering about a player, a past game or another issue involving the Bears? Senior writer Larry Mayer answers a variety of questions from fans on ChicagoBears.com.

I've read that Mitchell Trubisky is performing well in his second year in the offense, but I was wondering if you could explain specifically some things he's doing better.

With a much firmer grasp of the offense this year, Bears quarterback Mitchell Trubisky has been doing a better job this offseason of fixing pass protections and diagnosing what the defense is doing when it tries to disguise fronts, stunts and coverages. Here's what coach Matt Nagy had to say about Trubisky after Wednesday's minicamp practice: "Anybody that tells you that knows football and knows good quarterbacks, a lot of the reasons why they're successful is because they know how to create protection and help their O-line create protection to have matchups to be able to make the throws so that they can be more accurate."

I haven't heard about speedy receiver Marvin Hall, who signed with the Bears as a free agent earlier this offseason. How has he looked in practice?

Marvin Hall took advantage of some expanded reps in Wednesday's practice inside the Walter Payton Center and made some nice catches. (He got some extra work because veteran receiver Allen Robinson II was excused from the workout for personal reasons.) Hall spent the past two seasons with the Falcons, appearing in 24 games, all as a reserve, catching 12 passes for 209 yards and two touchdowns. The 5-10, 190-pounder served as Atlanta's primary kickoff returner last season, playing in all 16 contests and averaging 23.7 yards on 26 returns with a long of 53 yards. Here's what coach Matt Nagy said about Hall following Wednesday's practice: "He made a few mistakes early on. Not that it was really mental. It was more of just, 'Oh, I need to do that.' He ran a bench route instead of an in-route. And so after he made that mistake early on, he's been really good. He's a fast receiver. He's got really good hands. And for him just getting down the timing and understanding that he's where everybody else was last year learning this offense, so he's a little behind there. But he's picked it up great and I'm proud of him."

How have Cody Whitehair and James Daniels looked after they switched positions on the offensive line?

The swap has gone so well that coach Matt Nagy really hasn't given it a second thought. Asked about Cody Whitehair moving to left guard and James Daniels switching to center, coach Matt Nagy said: "It's probably really good that I don't even think about it. [Whitehair] has transitioned seamlessly to that. James has done the same thing. It's funny. I was actually talking to Cody right before practice [Wednesday] and really with our offensive line in general, those five guys that are there, they probably get the least amount of love from me right now, which is a good thing because they're the same crew. They're just working together. They just go about their business and they protect Mitch [Trubisky]."
