Seahawks defensive end Michael Bennett will be among the more heavily pursued players when free agency opens in March. Defensive ends coming off 8.5-sack seasons -- and 17.5 over the last two seasons -- don’t just hit the market; they are the market some offseasons. For that matter, he already is being recruited hard by the Bears – well, one Bear, anyhow – and not in violation of the rules that prohibit negotiations with another team’s pending free agents before Mar. 8. Bears tight end Martellus Bennett made no secret of his hope to have his older brother in Chicago, where an acute need exists for defensive linemen who can rush passers. Martellus went to Michael’s NFC Championship game in Seattle against San Francisco, “which will be pretty special,” Martellus said beforehand. “I haven’t gotten the chance to do that since we’ve been in the NFL. It’ll be a blessing to watch him play.” Martellus is using a recruiting “tactic” not exactly available to Phil Emery, Marc Trestman, Mel Tucker and others.
