The Texans made the most out of having officials present at Wednesday.
Officials, who oversaw the second day of the team's mandatory minicamp, made calls on some big plays during team drills. A diving touchdown catch by tight end C.J. Fieodorowicz ruled out of bounds was a topic of discussion even after practice.
"He did? Was he in bounds?" O'Brien said when asked about Fiedorowicz's catch. "No, so it doesn't count. It's like a long foul ball. Fiedorowicz is a very improved player."
Officials attended Wednesday's practice inside the Houston Methodist Training Center. A second-consecutive day of rain forced practice indoors, but it didn't dampen the activity level of two hours filled mostly with 11-on-11 drills. Players were more attentive to the rules, according to O'Brien.
"I think anytime you have the officials out there, there's an emphasis obviously on making sure that you're aligned properly, that you're staying on sides, that you understand that you can't- whether it's illegal contact or offensive pass interference in the secondary, and things like that because it's a passing camp," O'Brien said.
O'Brien wanted Tuesday's practice officiated as well, but impending bad weather and an earlier start time prevented it.
