"It was an amazing trip," Mullen told Dawgman.com about his time up at Washington. "I got to see the facilities and the school and I sat down and talked with coach (Bush) Hamdan about things for a little while.
"He just broke down what they are looking for from the players they are recruiting and what I can expect during the process and what it would be like for me as a player if I ended up going there."
Mullen walked away from his trip to Montlake without and offer from the Huskies, but he's hopeful one will come sooner-rather-than-later.
"It felt really good there and I feel like they could be close to offering me, but I don't want to be too confident or assume anything," Mullen said. "They didn't really even hint at an offer, but just talked me through the process and what they are looking for."
The talented wideout doesn't currently have any offers, but he's been in contact with a handful of schools and those are some of the schools he's looking at visiting at some point in the near future.
"The main schools I've been hearing from (besides Washington) are Washington State, Hawaii, Oregon State, Portland State and Eastern Washington," Mullen noted. "I haven't really broken down which schools I want to visit and which camps I will go to, but I'd like to get out and see as many schools as possible this spring and do a bunch of camps.
"Last year I did the Northwest Elite Camp and I'm hoping that I can do that one again. I am also probably going to hit one of the Nike Camps, but I am not sure which one."
Mullen is a big receiver who excels in the redzone and he said that's where things slow down for him.
"I think when it comes to playing in the redzone, that's where I am at my best," Mullen said. "I love to go up and get the ball, but I also have good footwork and that helps me in my route-running a lot and then I have good hands to bring the ball in."
As a junior last season, Mullen hauled in 22 receptions for 449 yards and six touchdowns.
