The New England Patriots signed 19 rookie free agents today –

P Ryan Allen (Louisiana Tech),
FB Ben Bartholomew (Tennessee),
DL Dewayne Cherrington (Mississippi State),
S Kanorris Davis (Troy),
OL Elvis Fisher (Missouri),
TE Brandon Ford (Clemson),
DL Cory Grissom (South Florida),
RB Quentin Hines (Akron),
CB Brandon Jones (Rutgers),
OL Josh Kline (Kent State),
OL Chris McDonald (Michigan State),
WR TJ Moe (Missouri),

LB Ian Sluss (Portland State),
OL Matt Stankiewitch (Penn State),
TE Zach Sudfeld (Nevada),
WR Kenbrell Thompkins (Cincinnati),
DL Joe Vellano (Maryland)
LS Mike Zupancic (Eastern Michigan).

The Patriots might have as good a track record finding undrafted free-agents who can contribute as they do finding guys in the draft.

Some key undrafted guys on their current roster? Kyle Arrington, Brandon Bolden, Dane Fletcher, Marcus Forston, Justin Francis, Kyle Love to name a few. As you can see from that list, three undrafted guys made the roster last year. So, who can find a role this year?

We already wrote on DL Cory Grissom as maybe being a steal since he was originally projected to go in the 3rd-5th round. Others that have gotten a lot of buzz include T.J. Moe and Joe Vellano.

Rookie minicamp begins today.
