Richardson's first contact with the Ravens was days after that night at the restaurant, a phone call with Harbaugh on a Sunday night that turned into a multi-hour conversation about life and football.
It ended with Harbaugh telling Richardson that he was going to talk to Newsome the next day and that he would be back in contact during the week.
Days later, Harbaugh called back with the news that led to the celebration inside Hall's living room, though Richardson's visit to Baltimore the following week didn't go as expected as he left without signing.
Richardson had trimmed down from around 235 pounds to 228 despite only limited work with McCoy to that point, but the 5-foot-9 Richardson weighed in at 238 in Baltimore after settling for fried chicken at Popeyes the night before and then eating a heavy breakfast that consisted of pancakes, grits and a breakfast wrap.
"I didn't think I was working out," Richardson said. "They were like, 'You ready to go work out?' I'm like, 'Work out?' That was right before the workout and I got weighed right before that. I was like, 'Oh my God.' And I jumped on the scale and I was like, 'Oh my God. I've been doing so good...'"
Still, Richardson said he got positive feedback following the workout, which included position drills and Richardson running the 40-yard dash.
Afterward, Newsome told Richardson to get his weight down, to come back at 225 pounds and, among other things, that "we really want you here."
Through continued work with McCoy and by following a diet plan constructed by McCoy, Richardson was down to 226 pounds early last week and weighed in at 218 pounds Thursday, three weeks after visiting Baltimore.
This is the lightest Richardson has been since high school.
"I feel good. I feel like the old high school Trent," said Richardson, who ran a 4.48 40-yard dash at 228 pounds at his Pro Day in 2012.
Richardson has gotten to a point that — after finishing a workout with McCoy on Monday — Richardson joked with McCoy, "That's all you got?"
"He's back," said McCoy, who was a senior at Alabama in 2009 when Richardson was a freshman. "With his focus the way it is, he looks like that freshman at Bama."
