With a daytime high of 98 degrees in Owings Mills according to Weather.com, staying cool at Ravens training camp was a challenge for the players and coaches on the practice fields. Wide receivers Torrey Smith and LaQuan Williams both dealt with leg cramps caused by dehydration, and at one point, free safety Ed Reed wondered aloud where the I.V. drips were. Fans who attended Thursday afternoon’s session were treated to popsicles.

Still, coach John Harbaugh said the hot and humid weather is a good barometer for how diligent the players were during the offseason.

“That’s what it’s all about,” he said. “That’s why guys need to be in great shape. That’s why you need to prepare in the offseason and to get yourself ready in the interim period before training camp. Camp is tough. Anybody that has played the game understands – training camp is tough. You start off in 95-degree weather, 95-percent humidity, and you end up with the snow blowing all around you. It’s one of the beauties of the game.”

Not surprisingly, Harbaugh described himself as a “summer guy” and said the heat is a vivid reminder of what’s expected from the players.

“It’s good to have hot weather,” he said. “It’s good to get yourself out there and get acclimated to it. All the doctors will tell you that you have to be in it to get used to it. It takes about a week to a week-and-a-half to get used to it. But you don’t want to be out here every day in it because that can be debilitating. So if we get a long period of hot weather, we’ll go in there and turn the air on and be smart about it.”
