Campanaro's six-day-a-week training focused on speed drills and other things that the scouts would be measuring at the NFL combine in late February.
He then turned heads with a 40-yard dash time of 4.46 seconds, a vertical leap of 39 inches, a 10-2 broad jump, a shuttle time of 4.01 seconds and 20 reps at 225 pounds on the bench press.
"The combine is always important, but for me it was especially big and I thought it went extremely well," Campanaro said. "Between the numbers I put up there and playing in the Senior Bowl, I think I was able to answer a lot of questions people had about me.
"I've received so many good vibes and so much good feedback from so many different teams the last couple months."
The Ravens are one of those teams. Campanaro had a formal interview with Ravens officials at the Senior Bowl in January, and an informal meeting at the NFL combine with new receivers coach Bobby Engram. In mid-April, he made the trip back home for a couple days to visit family and participate in the Ravens' local prospects workout day.
Campanaro said showcasing his talent for the hometown team was special. "It was definitely something I wanted to do, get a chance to come up and work out with the team after going to so many games growing up," he said. "I've been a fan since I was a kid, so it was pretty fun to be there working out for the coaching staff."
"The NFL game has changed a lot over the last five years to more of a spread offense passing style, which makes the slot receiver position very valuable," Van Deusen said. "Michael has the talents that many of the NFL slot receivers have, and he has better speed than most of them."
As for comparisons to a receiver such as Welker, Campanaro says it's flattering, but he a wants a chance to pave his own road.
"Being compared to those guys is a huge honor just because without a guy like Wes Welker, I wouldn't really be where I'm at today," he said. "He's kind of set a mold in the NFL for the position that we play. But I also try to express to teams that I'm more athletic than your typical guy playing in the slot and I think I have the potential to bring more of a home run threat than a lot of them.
"I think at the combine, especially, I got a great stage to show all the teams all the things I can do."
While he won't be at home for the draft, Campanaro says he does plan to host a party with friends and family in Miami, where he is continuing his workouts.
The first round is slated for Thursday, the second and third rounds scheduled for Friday and then rounds four-through-seven wrapping things up on Saturday. Campanaro's phone could ring any time between late Friday into Saturday.
"It's a waiting game now," Campanaro said. "But I guess when you think about it, I've been working and waiting for this moment since I first started playing. So really, what's a little bit longer at this point?"
