When you hit the bottom, you can only go up.

Unless there's something below the bottom, of course, but that means what you thought was the bottom was not really the bottom.

Anyway.

That's about the only way we can perceive the season that fifth tight end off the board in PPR formats last season, Davis didn't live up to the draft-day cost.

Or, to be blunt, he finished 35th in PPR scoring among tight ends.

So, now Davis is being selected as the 26th tight end in best-ball leagues, behind, well, just about everyone who has a semblance of a claim to a starting role.

Sure, Davis had injury issues of his own, and the 49ers offense was pyrite at best -- they ranked 22nd in schedule-adjusted just one red zone target, which he converted for a two-yard touchdown.

Blame the seventh-best quarterback rating (107.6) among all quarterbacks with at least 20 red zone attempts last season. He tossed just 19 total touchdowns last year, but 11 of them came inside the red zone.

Only one player caught more than two red zone touchdowns for the 49ers last year: Stevie Johnson, who is now a Charger. Michael Crabtree caught two, and he's a Raider.

In 2013, Davis scored eight red zone touchdowns while being targeted on 35.3 percent of the 49ers' red zone attempts -- the highest market share among tight ends in the past three seasons. In 2014, his share was just 2.3 percent, tied with teammate Vance McDonald.

Of course, new teammate Torrey Smith hauled in six red zone touchdowns last season, but that was his best mark in the past three years (he had five in 2012 and three in 2013). Simply put, the 49ers shouldn't have too many red zone threats to contend with Davis if he can return to his former glory.

And while Davis was absent in terms of red zone production, he certainly wasn't struggling for snaps. His 59.3 snaps per game ranked ninth among all tight ends last year, and his snap percentage of 78.4 ranked 11th. Combine that with a position-leading average depth of target of 12.4 yards among tight ends with at least 25 percent of team snaps played, and Davis showed potential even during a horrible year.

That depth of target was no fluke, either. Davis's average target depth was also tops at tight end in 2013 (14.3 yards) and second in 2012 (12.4).

That Draft-Day Cost, Though

Even if you're afraid of Kaepernick's bounceback potential, it's quite clear that Davis -- barring an extremely diminished role from new head coach Jim Tomsula's regime -- has the potential to return to some level of success in 2015. He has shown elite red zone potential before, and he's a rare downfield threat at the tight end position.

Even if he doesn't, with an average draft position of TE26, it won't matter if he doesn't realize that elite potential, but his ceiling is higher than his draft-day cost is letting on.
