BEREA, Ohio — With the midpoint of the season only two games away, nobody knows for sure how good, or bad, the Cleveland Browns really are.

One week after trouncing the Pittsburgh Steelers they were trounced themselves by the Jaguars on Sunday in Jacksonville 24-6. The Browns missed an opportunity to increase their record to 4-2 for the first time since 2001.

The Browns won two games in the final seconds and lost two on the final play. Those four games, coupled with a blowout victory and a blowout loss, leave the Browns dead even at 3-3 with back-to-back home games against the Raiders and Buccaneers up next. The Raiders are 0-6, but so were the Jaguars. The Browns will not take Oakland lightly.

“Offensively we took a huge step backward,” head coach Mike Pettine said. “We were soundly beaten. We know we have a lot of ground to make up, a lot of things to get corrected, then we’re on to the next one. We’re not going to dwell on it.”

Pettine and his coaching staff have a lot to figure out in the coming days, primarily what to do about an offensive line left porous because Pro Bowl center Alex Mack is done for the season after breaking his leg on Oct. 12 in the game against the Steelers. The injury forced starting right guard John Greco to move to center. Paul McQuistan came off the bench to play right guard.

The moves weakened the Browns at two positions because Greco does not play center as well as Mack and McQuistan isn’t as good as Greco. That was evident in the Jacksonville loss when the Browns were held to 69 yards rushing on 30 carries.

Pettine has options if he wants to make changes before playing the Raiders. He can activate Nick McDonald from the non-football injury list and then start McDonald at center and move Greco back to guard. The Jacksonville game was Greco’s first as the starting center.

Pettine could also keep Greco at center at start Vinston Painter at right guard. The Browns signed Painter from the Broncos practice squad on Sept. 2 because they believe he is a good fit for their zone-blocking scheme.

Quarterback Brian Hoyer had by far his worst game of the season, completing only 16 of 41 passes for 215 yards and one interception. He also lost the ball on a strip sack and threw 10 straight incomplete passes in one stretch through the second and third quarters.

Injuries have decimated the defensive line. End Phil Taylor (knee), nose tackle Ahtyba Rubin (ankle) and end Billy Winn (quad) were inactive. End Armonty Bryant (knee) was placed on injured reserve last week.

The injury to Rubin forced the Browns to activate Jacobbi McDaniel from the practice squad. Tight end Gerell Robinson was waived to make room on the roster for McDaniel.

Notes: Fullback Ray Agnew was waived Monday.

REPORT CARD VS. JAGUARS

–Passing offense: D – Brian Hoyer was off the mark several times, receivers dropped passes and Hoyer’s protection broke down all afternoon. Hoyer had a chance to pull the Browns through with a 65-yard pass play to Andrew Hawkins in the fourth quarter. But the Browns went backward on the next two plays and Hoyer threw an incomplete pass on third down. The Browns ended up punting. Hoyer was 16 of 41 for 215 yards.

Running offense: D – The passing offense struggled because the run offense could not get untracked. The Browns went into Jacksonville averaging 145 yards a game and managed just 69 yards on 30 carries. The offensive line got very little push on the stout Jacksonville defensive line. None of the Browns three running backs — Ben Tate, Isaiah Crowell or Terrance West — averaged even 3 yards a carry individually on a total of 28 carries.

–Passing defense: B – Safety Tashaun Gipson intercepted two passes and cornerback Buster Skrine picked off one. The Browns held Jacksonville quarterback Blake Bortles to a passer rating of 40.3 and 159 yards passing. However, a big reason the Jaguars won for the first time this season is that Bortles passed for 71 yards at the end of the first half to turn a 6-0 deficit into a 7-6 Jacksonville lead.

–Running defense: C- – Tackling problems that seemed to be fixed a week earlier against the Steelers cropped up again. The Browns had no answer for running back Denard Robinson, who rushed for 127 yards on 22 carries. Linebacker Barkevious Mingo is almost invisible in the Browns defense. The sixth pick of the 2013 draft made three tackles Sunday.

–Special teams: D – The most critical error in the game by the Browns was a muffed punt by Jordan Poyer at the Cleveland 2. He should have let the ball go into the end zone. Long snapper Christian Yount drew a holding penalty on a punt that went into the end zone. The mistake gave the Jaguars the ball on the 30 when the goal was to pin them inside the 5. Punt return has been a problem all season. Their longest return in 2014 is 8 yards.

–Coaching: D – Questionable coaching decisions hurt the Browns. They led 6-0 and had fourth down at the Jacksonville 24 late in the first half. The Jaguars had done nothing offensively. Instead of taking the field goal, Mike Pettine went for the first down and failed. The stop ignited the Jacksonville crowd and the Jaguars offense. Special teams coordinator Chris Tabor should have used Jim Leonhard instead of Poyer to field the fourth quarter punt inside the 5.
