We have poured over the known free agents-to-be but there are a crop of free agents that could very well become available even before free agency hits. Those are the players who are cut. In most cases those cuts are made prior to the start of free agency so as to clear up cap room.
Here are the players on offense who could become available that the Raiders should be watching for:
Matt Schaub QB Texans ($4 mil savings) - The Texans have moved on from Schaub and are ready to start anew. His release is forthcoming. A change of scenery might do him good.
Chris Johnson RB Titans ($6 mil saving) - He is still a pretty good NFL back although he no longer is worth his huge contract. Could be ideal change of pace back alongside Rashad Jennings.
Harvey Dahl G Rams ($4 mil savings) - Rams restructured his deal last year and now must consider cutting him before he is due a $2 million roster bonus.
Gabe Carimi G Bears - Carimi was already released, actually. The former first round pick is considered a bust as a tackle but played pretty well at guard. Definitely worth a look.
David Stewart RT Titans ($6.4 mil savings) - The Titans could use the $6.4 million in cap savings by cutting him. Stewart would be a hot commodity as a starting right tackle.
Eddie Royal WR Chargers ($4.5 mil savings) - In the last year of a 3-year deal which sees his salary jump to $4.5 million, which is too much for his services. He would be upgrade from Jacoby Ford.
Marcedes Lewis TE Jaguars ($5.45 mil savings) - A good tight end with the contract of an elite tight end. The California native could be cut and return to the Best Coast.
Zach Miller TE Seahawks ($5 mil savings) - The Raiders former leading receiver has his Super Bowl ring. He hasn't had the production expected though, and is set to get a $1 mil roster bonus on top of his already high price tag of $4.8 million.
