The Bills could potentially double-down on Diggs this offseason.
Trevon is the younger brother of recently-acquired wide receiver Stefon Diggs.
The two are five years apart in age, but came together when their father died of congestive heart failure when he was just 39.
"I was in the fourth grade," Trevon Diggs remembered at the NFL Combine in late February. "He was kind of young at the time, just getting into high school I want to say. He was kind of young, but over time he started to mature and see that I needed some help and some guidance because I'm his little brother at the end of the day. So he's been there for me, been helpful and I'm thankful."
"That's like my dad, honeslty."
That bond has continued as Trevon tries to follow Stefon into the NFL.
"I always ask him everything, no matter what," Trevon said. "Two o'clock in the morning I'm asking him questions. I'm calling him last night, every day, just asking him about his experiences, his process, how he managed it. So it's a lot of things that I ask him and he keep me up to cues with."
Trevon headed to the pros after an interesting four years at Alabama. He ended his time with the Crimson Tide as a 3rd team All-American after grabbing three interceptions, eight pass break-ups, and an interception and fumble returned for touchdowns.
But that's not where Diggs began, first seeing the field with Bama as an "athlete" playing wide receiver (11 receptions for 88 yards and a TD), safety (5 tackles and a forced fumble), and as a return man (7 kick returns for 23.7 YPR and 13 punt returns for 10 YPR).
"This is another thing my brother told me. He said 'You're going all the way to Alabama. You're going to have to compete. You're going to have to step it up.' So I went down there with the mindset that I'm trying to get on the field, someway, shape, or form. Whether it was special teams, offense, defense, I was trying to get on the field and that's exactly what I did."
He fully shifted to cornerback as a sophomore and started as a junior and senior., all while keep his offensive skills handy.
"I can tell what a receivers doing by where he's lined up," Diggs said. "I know the whole route tree. I know how many steps it takes to get into a route. I know what foot to put up when they're trying to run that route. So there's a lot of little things that I know that I can pick up on quicker, so it's really helpful. It's really helpful."
Diggs is a physical, press-corner at 6'1", 205, with great length and ball skills.
He says teams have told him he needs to remain disciplined in his technique, admitting he sometimes lets his physical traits overcome the proper form. Some evaluators also worry about his long speed.
While the only evaluations that matter now are those of NFL teams, Trevon is used to the fine eye of big bro.
"He always critiques me," Trevon said. "We never talk about the good things. We only talk about the bad things and the things we can do to get better. He always gives me tips and cues to work on my game and things to work on. I'm blessed to have that. I don't have someone patting me on the back all the time and telling me I'm doing good, I'm doing good. I got someone telling me let's get to work."
And whether or not the Diggs brothers reunite with the Bills, there will likely be an opportunity for them to go against each other on the field, just as they did as kids.
"I feel like it would be easy," Trevon joked.
Trevon Diggs is likely a 2nd round selection.
