Five problems the Miami Dolphins need to solve in training camp

As much as Dolphins coach Adam Gase loves his roster, he’s repeatedly painted it as a work in progress. There’s still plenty to figure out personnel-wise, and that process kicks into high gear when training camp opens Thursday morning.

As Gase approaches the start of a critical third season with Miami, here are five problems he has to solve over the next few weeks:

1. They need a backup quarterback.
It’s fine for the Dolphins to be optimistic about Ryan Tannehill’s knee, and there appears to be good cause for that, but they know better than to assume he’ll make it through all 16 games. They actually came out and said that in January, which made it perplexing that they did not secure a proven backup in the offseason. Gase says he’s supremely confidence in David Fales and/or Brock Osweiler as the backup — he seems to favor Fales — but both of them come with question marks.

2. Their linebacker corps must improve.
As a former linebackers coach, defensive coordinator Matt Burke must have been exasperated by how underwhelming the Dolphins were at that position last year. They’ve got a good start with Raekwon McMillan in the middle and Kiko Alonso on the outside, assuming they stay healthy, but there’s no certainty beyond those two. Stephone Anthony’s had an up-and-down career, Mike Hull and Chase Allen haven’t proven themselves as NFL starters, and it might take a while for draft picks Jerome Baker and Quentin Poling to materialize into contributors.

3. Kenyan Drake has to establish himself as a top weapon.
The Dolphins’ collection of skill players has a lot of good talent, but is there a great one among them? Drake’s speed and versatility, combined with Gase’s inventiveness, gives him a chance to stand out. When he took over as pretty much the only healthy running back available late last season, he closed the year with a league-best 444 yards (4.9 per carry) over the final five games. He also caught 17 passes for 150 yards during that span. But the jump from there to becoming a premier weapon is a big one, and it’ll take more than just physical ability.

4. There’s a big vacancy at kicker.
Kicker and punter are positions that fans (and teams, for that matter) sometimes take for granted, and that could hurt the Dolphins this season. They regret losing Cody Parkey in free agency and now move forward with seventh-rounder Jason Sanders competing against undrafted local product Greg Joseph. Neither seems to have an edge after their first three months in the organization, so training camp decide it.

5. Defensive end has to be an absolute strength.
The Dolphins’ salary cap ledger makes one thing undeniably clear: They value pass rushers above all else. It’s fine to spend big at that position, but they have to get results there. Robert Quinn and Andre Branch are the two biggest salary cap hits on the roster this year, combining for $21.4 million, and Cameron Wake is fifth at $9.6 million. Those three are eating up about 17 percent of Miami’s total spending, according to Spotrac. With a first line of Quinn and Wake followed by a second wave of Branch and Charles Harris, Miami needs to be in the top 10 in sacks this year.
