"It was a great visit, I really enjoyed myself there," Asiasi said. "The two biggest things that stood out were talking with TE Coach Jay Harbaugh and being around the players on the team.
"Coach Harbaugh was awesome. We sat down and watched film and I love how they use the tight end. They have a lot of different formations and move him around all over the field. The players there were great with me all weekend as well. It felt like a family there, they really took me in and the overall atmosphere was great. I had a great comfort level with everyone so it was a lot of fun."
Asiasi said spending time with head coach Jim Harbaugh was a big plus as well.
"He's a funny guy to be around," Asiasi said. "We spent a lot of time the first day I got there. He's such a competitive guy and always wants to win and improve. I think people only see that side but away from football, he's a really good guy and was fun to be around.
"I'm a big 49ers fan so I've been following him and know what a great coach he is. You can tell by this past season how much they missed him. He really changed the culture when he took over and he did the same thing with Michigan. I want to improve and get better and I know that would happen at Michigan playing for him."
Asiasi said distance won't play a factor in his decision.
"For me, my ultimate goal is to make the NFL so I'll go whever I think wil give me the best shot," Asiasi said. "That's not my only goal, there are other factors too but if I want to get my game to the next level, that could reequire me leaving home and I'm fine with that.
"Depth chart wise, they have some tight ends there, two seniors and some young guys but that doesn't bother me. You have to compete wherever you go and if there are other players there, you can learn from each other and make everyone better."
Asiasi will visit USC next weekend and then it will be decision time.
"I'll announce on Signing Day," Asiasi said. "Right now, all five schools are still in it. A few have inched ahead but I'm keeping that to myself for now.
"This week, I think everyone will be in for a home visit. I know Coach Pete from Washington, Coach Saban from Bama and Coach Harbaugh for sure. I think Coach Mora too but not positive and I'm not sure who from USC but I'm sure they'll be in. It's going to be a tough decision but February 3rd, I'll be ready to make my announcement."
