SANTA CLARA, Calif. -- The San Francisco 49ers' coaching search is entering its second week with the team ostensibly zeroing in on Cincinnati Bengals offensive coordinator and former Oakland Raiders head coach Hue Jackson. But no agreement was announced Sunday night and unless something comes to fruition Monday, it’s hard to see anything being announced before Thursday, with CEO Jed York expected to attend the Los Angeles relocation meetings in Houston on Tuesday and Wednesday.

An updated quick glance at those the Niners have already interviewed, noting that all five have offensive backgrounds, which makes sense considering the 49ers had the No. 31-ranked total offense in the league and was also the NFL’s lowest scoring team…

Hue Jackson: The man in charge of the No. 15-ranked unit in the NFL this past season spent five hours interviewing with the Niners on Sunday and then more time interviewing with the Cleveland Browns before calling it a night without an offer from either team, per the NFL Network. And per reports, the New York Giants might want to get involved with Jackson on Monday. It’s called leverage and right now, Jackson, 50, seems to have all if it. Here’s something else to chew on: if Marvin Lewis pays for the Bengals playoff meltdown with his job, might Jackson be the logical candidate to ascend as Cincinnati’s head coach?

Chip Kelly: The former Philadelphia Eagles coach met with the 49ers on Thursday and he could be the most intriguing candidate given the way he might be able to use quarterback Colin Kaepernick in his wide-open offense. Then again, wouldn’t the Tennessee Titans be a better fit for Kelly, 52, given his previous relationship with Marcus Mariota at Oregon?

Anthony Lynn: The Buffalo Bills assistant head coach/running backs coach interviewed with the Niners on Thursday. The Bills had the No. 1 rushing offense in the NFL this season, averaging 152.0 yards per game, and while Lynn, 47, may not really be seen as a top candidate but might be in line for an assistant position. What would that mean for longtime RB coach Tom Rathman?

John DeFilippo: Cleveland Browns offensive coordinator interviewed on Friday, has only been a coordinator for one year and the Browns were 25th in total offense, but they did drop 481 yards, including 230 on the ground, while racking up 28 first downs against the 49ers on Dec. 13. And while he may be a longshot, DeFilippo, 37, has cut his NFL assistant teeth as a QB coach, working with the likes of JaMarcus Russell, Mark Sanchez, Terrelle Pryor, Derek Carr and Johnny Manziel. So you think he’d be intimidated by the prospect of dealing with Colin Kaepernick?

Dirk Koetter: The Tampa Bay Buccaneers offensive coordinator interviewed with the Niners on Saturday in what may have been more of an informational sitdown given that Koetter, 56, is seen as the natural successor to the fired Lovie Smith in Tampa Bay. The Buccaneers had the No. 5-ranked total offense in the league last season and he has a history of working with quarterbacks, from Blaine Gabbert with the Jacksonville Jaguars to Matt Ryan with the Atlanta Falcons to last year’s No. 1 overall pick Jameis Winston in Tampa Bay.
