When he was traded, he had one REALLY good year left in him, which was his first in Miami.
But I agree, he should've hung it up at 35.
Seau will always be remembered as a Charger ... he should have left the NFL when he was still on top. One good year at Miami out of three wasn't worth it to him.
Looks like he may get one more shot at a ring as a situational linebacker in New England, filling a role that in the recent past has been done by Brian Cox and Roman Phifer.
