BOSTON (CBS) –  It’s not your typical classroom. They’re not your typical teachers. It’s where you go after failing all year. It’s Gresh and Zo’s NFL Summer School on 98.5 The Sports Hub!

The summer school tour rolls on and heads west to San Diego, where Andy Gresh and Mike Flynn break down and preview the upcoming 2014 season for the Chargers.

Taking Attendance:

The Chargers signed running back Donald Brown in free agency, drafted cornerback Jason Verrett with their first round pick and also grabbed linebacker Jeremiah Attaochu.

Gresh: “Donald Brown is a great depth signing. Ryan Mathews gets hurt every year and Danny Woodhead can only give you so much. For me it comes down to can you establish a legitimate running game, and can you develop a tight end behind Antonio Gates? Because he’s getting up there in age. I like this team a lot.”

Pop Quiz:

How much of a scare can the Chargers give the Broncos?

Gresh: “I think the Chargers at home will give them a run for their money. I think in Denver the Broncos should be a pretty healthy favorite. They’re not ready to be with the Broncos just yet, but you’ve got to lump them in with the playoff mix. I like them better than Kansas City.”

Flynn: “I think in a one-game playoff the Chargers would give Denver all they can handle. But over the course of the season it’s still Denver.”

Fantasy 101:

Would you take Philip Rivers as your starting fantasy QB?

Gresh: “Yes I would. At the end of the day he’s going to get you 30-35 touchdowns and 4,000 yards. He’s a middle of the pack kind of starter, but I wouldn’t mind having him. If I’m drafting big in other positions and I’m sitting there in round four and he’s still on the board, I’m taking him.”

Flynn: “32 touchdowns, 4,500 yards and another year in that system? He’s got weapons, so yeah, absolutely he’ll put up numbers.”

Expectations for Ryan Mathews in 2014?

Gresh: “He should be a 1,200 yard back and be able to give you what Stevan Ridley gives you. The problem is he’s a pane of glass and just gets hurt too often.”

Flynn: “I would look elsewhere.”

Final Grade:

Last year the Chargers went 9-7. Year before that? 7-9. Vegas has set the over/under at 8.5 wins. Where do they finish and do they make the playoffs?

Gresh: “They catch some pretty bad breaks in terms of away games and trips they have to make across the country. Hit me I’m going over. I’m gonna say they get to 9 wins and be on the fringe of the playoffs. They’re slow starters but strong finishers.”

Flynn: “I’m gonna go under. Eight wins.”
