Not seeing it, Schobel is 33, they just dumped one 33 yr old, and unless Belichick is serious about running the 4-3, it is a expensive square peg into round hole situation. I do think Schobel will land somewhere unexpected, meaning not with the Texans, but the Pats do not make much sense.
New England needs pass rushers. Makes sense from the perspective of acquiring a pass rusher, even if you need a fourth down lineman to do it.
Texans are loaded at the DE position so Schobel makes little sense to go there barring injury, however with the Pats and Broncos in dire need of passrushers, Schobel has options above a Vet minimum hometown discount deal with the Texans.
