Baltimore Ravens at Pittsburgh Steelers

The Baltimore Ravens come into Pittsburgh for a tough road contest and sporting a shocking record of 0-3, but that hasn't made them underdogs against a 2-1 Steelers squad.

Of course, that largely has to do with the tough loss of Roethlisberger last weekend, as he suffered a sprained MCL that should keep him out "a number of weeks," head coach Mike Tomlin told Pittsburgh Post-Gazette's Sam Werner. Vick gets the start for Pittsburgh, who hopes to put his turnover issues from the last several years to bed.

The Steelers offense has been electric with Antonio Brown and the return of Le'Veon Bell, but Vick will need to deal with the Ravens pass rush to get the ball to those guys. Then it's up to the defense to hold up, which will be easier said than done without an impact linebacker in the fold, as Ian Rapoport of NFL Network noted:

Not only are the Steelers short-handed on defense, but they already have struggled mightily against the deep ball this season. They have given up over 255 yards per game through the air, were lit up by Tom Brady and even allowed big plays to the struggling Colin Kaepernick.

As for Baltimore, it may be 0-3, but the offense should be plenty confident after hanging 33 on Oakland and exploding late against the Bengals. Joe Flacco is due for another big day with Steve Smith Sr. wreaking havoc on the Steelers' subpar secondary, which is why the Ravens should be considered favorites in this one.

New York Giants at Buffalo Bills

This is just one of two matchups this weekend split down the middle by the four above experts, and it's not hard to see why.

Head coach Rex Ryan's arrival in Buffalo has paid immediate dividends, turning a potential-filled roster into one that has started 2-1—with the only loss a late failed comeback attempt against the New England Patriots. Where the defense has faltered, the offense has more than picked up in its place, with Tyrod Taylor and LeSean McCoy torching opposing defenses.

However, McCoy's availability for Week 4 doesn't look great, as ESPN.com's Mike Rodak noted:

The Bills should still be able to establish the run with a boisterous offensive line and promising rookie Karlos Williams, but not having the primary rusher will hurt against a Giants defense that allows yards through the air much more than on the ground. That will put the onus on Taylor to make things happen through the air.

After blowing a pair of double-digit leads in the fourth quarters of their opening two games, the Giants held off the Washington Redskins last weekend. A much stiffer test comes this weekend in Buffalo, and the G-Men better be prepared for a 60-minute battle.
