Chicago Bears: DE Lamarr Houston
This came down to either Houston or Willie Young, the other defensive end signed by the Bears during the first week. While Young was a tremendous value signing, Houston gets the nod because he's the better overall player. The Bears needed help against the run and getting to the quarterback, and Houston provides quality in doing both. At just 27 years old, he should be just entering his prime.
Detroit Lions: WR Golden Tate
Finally, the Lions have a capable No. 2 receiver behind Calvin Johnson. Tate remains underappreciated because he played in a run-heavy offense in Seattle, but he could blow up in Detroit. Few receivers have a better combination of sure-handedness (just five drops the last three seasons) and yards-after-the-catch ability. And now he'll face the soft coverages that come with playing alongside the game's best receiver. He could be the final piece for a Lions offense that should be dominant once again in 2014.
Green Bay Packers: DE Julius Peppers
Rarely does general manager Ted Thompson make a splash in free agency, but when he does, he usually hits. Peppers is 34 and in decline, but he still has rare size and athleticism. A change of scenery could recharge his batteries. The Packers will use him in a variety of roles, from the 5-technique to outside linebacker to interior nickel rusher. If properly motivated, Peppers can be a disruptive addition to a Packers front seven that needed the boost.
Minnesota Vikings: NT Linval Joseph
Cornerback Captain Munnerlyn was a fantastic find and value, but Joseph is Minnesota's best addition because he fills a huge need at nose tackle and Mike Zimmer's defense depends on talent up front. Powerful, with long arms and a quick first step, the 323-pound Joseph has everything you want in a true nose tackle. Pat Williams 2.0? Possibly. He'll do all the dirty work for a Vikings defensive line that has the potential to be one of the NFC's best in 2014.
