But as a converted tight end from receiver, his blocking ability is what he's been hard at work at as well.
"I think he's better than we thought," Bischoff said. "I think his fundamentals are clean, his want to is there. All you ever ask of a blocker is a willingness and we can take it from there.
"If they have a willingness, then you got to hone in on the fundamentals and help them grow," Bischoff added. "But if they don't have a willingness, that's a challenge. He has a willingness."
It's something that will be better to evaluate once the pads come on next month, but the willingness has been there so far.
Gadsden doesn't just want to be a receiving tight end, he wants to do it all.
"It should probably be every player's goal to be an every down player," Gadsden said. "If you're a football player, you should want to play football at all times, so you just go about it like I said before, being a sponge, taking everything that your coaches have given to you and just using it, using the opportunity.
"You might not get a lot of reps one day but you got to make the most of those reps," he added. "You get only so many reps every game so you want to make the most of it, you want to do the best you can every single time you get out there."
There's still a lot left between now and the beginning of the season, but Gadsden has been doing all he can to make sure he's in the right place when the time comes.
The rookie tight end has made his mark so far — but next month's training camp is something he's looking forward to show even more of what he's capable of.
"I'm going to give it my best every chance I get on the field," Gadsden said. "We still got camp to go, and we still got to put the pads on so that's when you have to show who you are and show how good you are as an all-around player.
He added: "Once you get those on, that'll give a better representation of me."
