If you're looking into acquiring Matt Hasselbeck on the waiver wire, one or two things have happened.

1. You're desperate.

2. You drafted Brett Favre as your starting quarterback. If this is the case, No. 1 also applies.

If you have Favre and didn't draft a quality backup, Hasselbeck is a decent one-week option with Favre on a bye.

The Seahawks play Sunday at the Rams, who rank 24th against the pass, allowing 730 yards in three games.

All of which brings us to our free-agent selections for Week 4. The picks are available in more than 50 percent of the leagues on ESPN.com -- this week, they are available in at least 66 percent.

QB: Matt Hasselbeck, Seahawks (25.3 percent)

Mark Sanchez is available in 53 percent of the ESPN formats, but I'd rather have Hasselbeck this week. He hasn't been very good since 2007, but he's averaging 208 passing yards per game this season and could throw for a couple of scores vs. St. Louis.

RB: BenJarvus Green-Ellis, Patriots (28.7 percent)

Someone has to get the carries in New England -- and fortunately for Green-Ellis, Fred Taylor left last week's game with a toe injury and missed practice Wednesday, Kevin Faulk is on injured reserve and Laurence Maroney is in Denver. Green-Ellis had 16 carries for 98 yards and a touchdown last week. Sunday, he'll face a Dolphins defense that is allowing 117.3 rushing yards per game, 4.5 yards per attempt and has given up two rushing TDs this season.

WR: Brandon Lloyd, Broncos (33.6 percent)

He's been Denver's best receiver, and I have reluctantly jumped aboard the bandwagon after a three-week stretch in which he's had two games with at least 117 yards. Lloyd has 14 receptions for 339 yards and a score. Don't expect a huge game Sunday at the Titans, who are the league's fifth-best pass defense and have given up only one TD toss (compared to three interceptions).

WR: Lance Moore, Saints (12.2 percent)

He caught six passes for 149 yards and two scores last week, and as I wrote late Sunday night, he should get a lot more chances with Reggie Bush out. Moore, who had three catches in New Orleans' first two games, was productive in 2008 (79 receptions, 928 yards, 10 TDs), and his Week 3 was better than the three-game totals for both Devery Henderson (seven catches, 89 yards) and Robert Meachem (four catches, 38 yards).

Of the three receivers on this list, Moore has the best Week 3 matchup. The Panthers have allowed six touchdown passes (the fifth-most) in three games.

WR: Jabar Gaffney, Broncos (19.0 percent)

That crafty Kyle Orton is spreading the ball around in Denver -- Gaffney has 26 targets, Eddie Royal 24 and Lloyd 22. Gaffney has 17 receptions for 189 yards, but because of the matchup at Tennessee, is the worst play of the three wideouts in this space.

TE: Aaron Hernandez, Patriots (23.5 percent)

The rookie has 12 receptions for 166 yards the last two weeks, and he is averaging 16.2 yards per catch on the season. He has 13 receptions on 15 targets (the erratic Randy Moss has nine on 21 targets), and he could be a top-10 tight end in PPR formats. Monday, the Pats play at Miami, which ranks ninth against the pass.

TE: John Carlson, Seahawks (27.1 percent)

He's surprisingly undervalued after averaging 53 receptions and six touchdowns in his first two NFL seasons. Carlson has 10 catches the last two weeks, and he had five for 61 yards and a TD in Week 3. His 24 targets are eight more than any other Seattle receiver.

Carlson also has a much more favorable Week 4 matchup than Hernandez. The aforementioned Rams are allowing 243 passing yards per game.
