WR James Jones released, QB Terrelle Pryor, CB Alfonzo Dennard waived

The NFL Draft and undrafted free agency might be hitting our rear view mirror this week, but that does not mean roster additions are complete. NFL teams are adding and dropping players left and right, opening the door for some changes. Three recent transactions are particularly interesting for San Francisco 49ers fans.

On Monday, the Oakland Raiders released wide receiver James Jones. On Tuesday, the New England Patriots waived Alfonzo Dennard and the Kansas City Chiefs waived quarterback Terrelle Pryor . Jones is immediately a free agent due to his longer veteran status, while Dennard and Pryor both have to first clear waivers.

Pryor is the most interesting of this group for a reported previous connection to the 49ers. A year ago, the Seattle Seahawks acquired Pryor via trade, and there was a report the 49ers were in the mix for him. The Seahawks gave up a seventh round pick, and reports indicated the 49ers were not willing to give up more than a "conditional" seventh round pick. The 49ers have three quarterbacks on their roster, including Colin Kaepernick, Blaine Gabbert and newly signed UDFA Dylan Thompson. The team will add at least one more quarterback, so we'll see if they put a claim in for Pryor.

The Raiders released James Jones after signing Michael Crabtree and drafting Amari Cooper. Derek Carr can use more weapons, but Jones was kind of a Crabtree duplicate, and really just not necessary at this point. The 49ers currently have 12 wide receivers on their roster following the drafting of DeAndre Smelter and the signing of five UDFA wide receivers. I don't expect the 49ers to sign Jones, but if they want more veteran presence beyond Anquan Boldin and Torrey Smith, maybe they kick the tires.

The Patriots waived Alfonzo Dennard following a poor 2014 season. The Patriots selected Dennard in the seventh round of the 2012 NFL Draft after he slipped due to various problems. He was originally projected as a day two or early day three pick but an assault charge for punching a cop caused him to slip. Once selected, he got off to a strong start in 2012. He regressed in 2013 and was off the radar in 2014, playing in only six games. The 49ers seemed to think they are in good shape at cornerback, drafting none this past weekend, but maybe they take a chance with a waiver claim on Dennard.
