Lions notes: Detroit’s offensive line ranks 15th overall per PFF

• Pro Football Focus ranked all 32 offensive lines through the first quarter of the season. The Detroit Lions’ line ranks 15th overall. Here’s what PFF had to say about them:

Rookie Taylor Decker has been okay at tackle so far this season, allowing three sacks and 13 total pressures while being asked to pass block 187 times already. The weak link so far has been G Laken Tomlinson, whose run blocking has been poor, but he’s actually been solid in pass protection—which has been more important for a team passing far more than they are running. Riley Reiff has been performing well as a run blocker, but has been only average in pass protection.

• Jim Caldwell is now the fourth-most likely NFL coach to be the first fired in 2016, according to sports betting site Bovada.

• No.

• Justin Rogers has a good replay of how Ezekiel Ansah came down with an ankle injury against the Tennessee Titans:

• Football Outsiders’ Week 4 rankings are out and finally adjust for opposing defenses. Unfortunately that adjustment, combined with the loss to the Bears, have made the Lions plummet in rankings. They now have the worst defense in the league, the 10th ranked offense and the best special teams unit in the league. Those numbers combine an overall ranking of 26th.

• Stephen Tulloch, who is now with the Eagles, will face his former team on Sunday. The veteran linebacker said on a conference call on Wednesday that he holds no animosity toward the Lions after the drawn-out process of releasing him this offseason.

• Charismatic punter Sam Martin answered Twitter question on this week’s version of #AskALion. His hints at a planned touchdown celebration but doesn’t reveal what it is.
