Given his propensity for getting sidetracked in curious directions recently, when Ravens coach John Harbaugh says something is "interesting — I guess — probably," it's time to take notice.
Early in training camp, he transitioned from talking about rookie tight end Maxx Williams being with the Ravens to catch passes, to his father going to the hospital for a hernia surgery and needing to remind the nurses making him fill out end-of-life paperwork that he was there to live, not die.
On Saturday, he went from pleading for open lines of communication between the NFL's officials and the league about their training camp availability to railing against partisan politics and immigration, saying America should "build the wall."
So, it seemed almost too natural a transition when he turned the topic of rookie guard Robert Myers' return to no-contact drills, following a concussion, to second-year guard John Urschel, who is out with the same injury, suffered the same day as Myers, Aug. 6.
Harbaugh said Urschel is "getting closer and closer," then related a story that shouldn't surprise anyone about the Ravens' resident brilliant mathematician.
"You're told when you get a concussion not to listen to certain things, not to read certain things, not to study certain things, not to do some certain things that might hurt the concussion part of the brain there," Harbaugh said. "So, my man goes out the second day afterwards and does high-level math problems just to see where he's at.
He continued: "I'm going to tell the guys tonight in the meeting, 'Listen, guys, for all you guys that may get a little concussion issue … You want to go out and do the high-level math? You want to do those trigonomic [sic], algebraic equations? We're putting an end to that right now on our team. We'll have no more of that.'"
It's unclear whether Urschel, the team's top reserve guard and a candidate to also be the deputy at center, was affected much by his academic exercise. Both math and football are his outlets, so losing both because of a scary head injury that left him on the turf for several minutes would be a tough pill to swallow.
And it's unclear that whatever math he was doing was much affected by the injury. Harbaugh said he didn't check.
"I wouldn't know the difference," he said.
