FOXBORO -- The Patriots announced on Thursday that they have signed rookie defensive end Deatrich Wise, who was taken in the fourth round of last month's draft. 

Wise is the second of New England's four picks to sign. Seventh-round offensive tackle Conor McDermott made things official soon after he was selected. Third-round defensive end Derek Rivers and third-round offensive tackle Tony Garcia have yet to ink their contracts. 

Since the last collective bargaining agreement between the NFL and its players, there isn't much to negotiate in terms of pay. Each pick has been assigned a value, meaning the amount of money a draft choice is given is preset. 

There are, however, other issues that are negotiated and can take some time. Deferrals of bonus payments, for instance, can be a sticking point (as they were with Joey Bosa and the Chargers last season). Offset language, allowing teams to recover guarantees if a player is released and signs elsewhere, can also take some time to hammer out.

Wise, who met with reporters on Thursday and smiled wide as he spoke about how he's adjusting to life as a pro, seemed to have a relatively easy time getting those elements ironed out and now he's put pen to paper.
