What you know about Joe Kasper to this point likely has little to do with the exceptional job he’s done coaching in the Eagles’ defensive secondary for the four seasons, including the 2024 and 225 campaigns. Instead, you know him because he’s gone viral as the coach who holds the tackling bag and who, along with the bag, gets taken to the mat during practice by players working on their form.
The safeties coach in ’24 and ’25, Kasper is now the team’s defensive passing game coordinator and coaching up the safeties is still a large part of his responsibilities. He is a rising young coach who has learned, and grown, working with coordinator Vic Fangio, eagerly learning everything he can about the NFL’s best defensive mind.
“The thing about working with Vic that has been except exceptionally awesome for me is just the learning about the process,you know, the process of how he goes about week to week, developing players from, you know, taking what we’re working on right now and how that stacks on top of what we’re going to work on at Training Camp and how we’re going to evolve and change things.The best part about Vic is that he’s constantly evolving and changing.
“So to be exposed to that, I think is awesome and awesome for me.He’s seen that process, that evolution year to year, week to week and how we tweak things and people sometimes pick up on it and hopefully never do and sometimes don’t and how we take advantage of that.Seeing that process is really cool.”
All of that process is revealed when the regular season begins, and then it is a week-to-week, play-to-play chess match that Fangio relishes and young coaches like Kasper study.
“How that comes to life on game day – how does that process play out in the offseason when you have more time to study and develop?Yeah, well, we try new things. We try things. We study other teams. We look at copious amounts of film and we try and decide what marries best to what other teams do.
“Can we steal something from somebody else? Do we understand what they’re doing? Can we pick and choose where it can help us?And we try things, you know, you try things and you see what works and you see what doesn’t work.And you try things into Training Camp. You try things, you know, into the season that you try and compliment your guys and and see if this can this is just something we love and we’re lean on. And we have our staples, you know, in our bread and butter that we hang our hat on.”
