The New England Patriots are less than one day into free agency, and the likes of linebacker Colin McCarthy and edge-rusher Jabaal Sheard have made visits thus far.

But so has the Patriots head coach.

On Wednesday morning, Bill Belichick was back on the scouting trail. He was alongside the Cincinnati Bengals’ Marvin Lewis and the Pittsburgh Steelers’ Mike Tomlin at the University of Louisville pro day, the Cardinals football program announced.

A wide net of Louisville prospects could be of interest to the Patriots heading into the 2015 NFL draft. And the organization had formal interviews with offensive tackle Jamon Brown and running back Michael Dyer at the combine last month.

But some other Cardinals of positional intrigue for New England include potential first-round wideout DeVante Parker, as well as guard John Miller, safeties Gerod Holliman and James Sample, outside linebacker Lorenzo Mauldin, running back Dominique Brown and cornerback Charles Gaines.

Whether or not that intrigue leads to more remains to be seen, as Belichick was with director of player personnel Nick Caserio and coaching assistant Michael Lombardi on a tour of the Southeast schools last week. Yet this week, with all the movement taking place across the league, Belichick elected to head to Louisville.

And Caserio elected to head to Rutgers.

The Patriots were among all 32 teams at the Scarlet Knights’ pro day, also held on Wednesday, according to NJ.com’s Dan Duggan.

Rutgers tight end Tyler Kroft is seen as a potential third- or fourth-round pick in less than two months, and it’s worth noting that Patriots offensive coordinator Josh McDaniels’ brother, Ben, is the new offensive coordinator for the Scarlet Knights.
