And the most prominent undrafted free agent already has a home.

Former Boston College LB Mark Herzlich is going to the Giants.

"I thought New York was my best opportunity to make the team as well as expand my role throughout the season," Herzlich said.

The Giants were more than willing to take a flyer on the cancer survivor.

"He's a great kid. He's certainly had his share of obstacles to overcome," owner John Mara said. "We wanted to give him an opportunity."

Herzlich tweeted the following Tuesday morning:

Decision is made I will be a #GIANT can't wait to get to #NYC. Thank you for everything. ... Mark Herzlich is a New York Giant!

Herzlich, the ACC's defensive player of the year in 2008 (110 tackles, 6 INTs), missed the following season while battling Ewing's Sarcoma (a bone cancer) in his left femur. He returned to play for BC in 2010 (65 tackles, 4 INTs) but admittedly is still working to recapture his pre-cancer form, which likely would have earned him a first-round grade.

"I definitely am confident that can happen and will happen shortly," he said. "It's all about work and learning, and that's what I'm going to do now."

He could be a perfect fit as a strong-side linebacker in the Giants' 4-3 defense, which could use youth and depth in its linebacking corps. Herzlich is very good in coverage, a skill that could aid him in a division featuring Cowboys TE Jason Witten and Eagles RB LeSean McCoy, who's often deployed on screens.

Herzlich said on NFL Network that he also strongly considered joining the Eagles and Ravens.

Former Delaware QB Pat Devlin is another highly regarded undrafted rookie to sign, according to ESPN. Devlin, who threw for more than 3,000 yards and 22 TDs last season, goes to Miami and could compete with Dolphins incumbent Chad Henne for playing time.
