When deciding what quarterbacks to start or sit in any given fantasy week, you obviously need to look at the opponent.

And through four weeks of the season already done, we’re starting to see some trends.

Below you’ll find the best and worst in the NFL when it comes to opponent completion percentage, something you should be looking at every week when making your roster decisions.

The easiest to complete passes on:

Detroit Lions — 99 for 127 (78%)
St. Louis Rams — 109 for 144 (75.7%)
San Francisco 49ers — 86 for 123 (69.9%)

And now for the toughest to pass on:

New York Jets — 72 for 141 (51.1%)
Tennessee Titans — 42 for 78 (53.8%)
Green Bay Packers — 74 for 131 (56.5%)

Here’s our version of start and sit: “He Will Shine” and “Show Him the Pine.”


He Will Shine

Marcus Mariota, Titans, vs. Bills

Mariota is not playing like a rookie. And I’m shocked because he doesn’t have much of a running game, nor does he have a completely reliable stable of receivers outside of Kendall Wright and Delanie Walker. He’s just playing smart and getting the job done, much like every quarterback who faces the Bills. Buffalo has allowed the 4th-most passing yards in the league and 2nd-most touchdown passes. I understand Rex Ryan traditionally eats rookie QBs for breakfast, but Mariota should certainly put up solid numbers.

Josh McCown, Browns, at Ravens

Don’t look now, but the Browns actually have a passing game. Since returning to the starting lineup 2 games, McCown has 4 TD passes and is averaging nearly 350 yards. That is not a typo. And the Ravens’s secondary is average-at-best, allowing Andy Dalton (383 yards, 3 TDs) and Derek Carr (351, 3) to absolutely torch them. If you’re in a pinch at the QB spot, you could do worse than McCown. Probably not a whole lot, but you could.

Alex Smith, Chiefs, vs. Bears

Smith has just a single touchdown toss since throwing 3 in Week 1, but he’s getting the chances as he’s attempting nearly 36 passes per game. The Bears just might help Smith get a couple of 6-pointers Sunday as they’ve allowed 10 TD passes on the season. The only team that has allowed more? The Chiefs with 11. That’s why if you keep reading you’ll also see Jay Cutler’s name as a recommended start.

Jay Cutler, Bears, at Chiefs
Sam Bradford, Eagles, vs. Saints



Show Him the Pine

Derek Carr, Raiders, vs. Broncos

I like Carr. A lot. Just not this week. The Broncos lead the NFL in fewest touchdown passes allowed (2), most sacks by (18) and are tied for third with 6 interceptions. Carr has built quite a rapport with Amari Cooper and Michael Crabtree in such a short time, but this is a very risky spot for the second-year QB.

Joe Flacco, Ravens, vs. Browns

With Steve Smith out for at least a game (back), Flacco heads into the Browns matchup with probably the most unproven receiving corps in the NFL. Kamar Aiken? Marlon Brown? Darren Waller? Wolfgang von Schweinsteiger? OK, made the last one up, but you get the point. Cupboard is rather empty at the moment. The Ravens are going to have zero problem running on the Browns, so expect Justin Forsett to the major beneficiary.

Matthew Stafford, Lions, vs. Cardinals

Stafford has thrown just 1 touchdown over the past 2 games and now faces a Cardinals unit which has allowed just 5. Albeit, 3 came last week vs. Nick Foles and the Rams, but that was more of an aberration. Bottom line is the Detroit offense is out of sync right now, even with Calvin Johnson and Golden Tate. And now Stafford will be without emerging TE Eric Ebron (knee).
