A Legacy of Law and Order: Why We Love ‘Blue Bloods’

Season 1 vs. Season 14: The Side-by-Side You Didn’t Know You Needed

Let’s compare how the characters looked in Season 1 versus now in Season 14—and trust us, some of these are jaw-dropping.

Tom Selleck as Frank Reagan: The Steady Hand

Then: Tom Selleck came into the role already a legend—mustache, charisma, and all.

Now: At 79, he’s still the pillar of the show. His iconic mustache is untouched, though his character has taken on a more reflective tone. Aging gracefully? Absolutely.

Bridget Moynahan as Erin Reagan: From Prosecutor to Powerhouse

Then: In Season 1, Erin was a smart and cautious ADA trying to raise her daughter.

Donnie Wahlberg as Danny Reagan: The Hot-Headed Detective

Then: Young, reckless, and emotionally driven.

Now: Still emotional—but wiser. Donnie brings depth to Danny’s trauma and resilience. And yes, he still rocks that NYPD badge like a champ.

Will Estes as Jamie Reagan: From Rookie to Sergeant

Then: Jamie was fresh out of Harvard Law and NYPD training.

Now: He’s matured into a steady leader. The baby face is gone, replaced with serious gravitas—and the chemistry with Eddie? 🔥
