Although the San Diego Chargers first string offense played just one series on Thursday against the Seattle Seahawks, we got to see a decent variety of play concepts. However, before we go forward, let's remember how the Erhardt/Perkins offense operates.
A concept is a group of players running a set of routes. For instance, a concept would be two eligible receivers on one side of the formation running a pair of slants, and another concept would be three eligible receivers running a corner, post, and go on the other side.
Each concept has a name, chosen by each team. Thus, a play might have a name such as Mike & Ike (Mike the double slants, Ike the corner, post, go). The concept can be run by WRs, TEs, RBs, or any combination thereof.
First, a couple of general observations:
- It seemed clear that McCoy and Whisenhunt were primarily concerned with keeping the offense "on schedule." There were no "boom or bust" plays, and until the final 3rd down of the drive, the Chargers never faced a 3rd and long situation.
- In my opinion, Philip Rivers doesn't look comfortable with this offense and the quicker throws it requires. He appears to still be in the Coryell offense mode of looking for the downfield play first, and holds the ball longer than necessary.
Anyhow, on to the plays from the first possession. For a more detailed breakdown on the results of each play, check out Kyle's article from yesterday.
"12" personnel. Rivers holds the ball a bit too long and nearly misses Eddie Royal on the slant, but Royal bails him out with a great catch and a 1st down. A quicker and more accurate throw may generate some YAC.
"21" personnel (2 RB, 1 TE, 2 WR). This is the first appearance of a bunch formation. The bunch is a staple of the Pittsburgh Steelers offense, recalling Whisenhunt's time calling plays for the Steelers. The crossing action of Royal and FB Le'Ron McClain creates confusion for the Seahawks defense, and Rivers gets an easy 1st down throw to TE John Phillips.
"12" personnel. This play provides the first evidence of concept-based passing (you'll see the Cross + Dig + Cross concept again shortly). Rivers has a quick dig to Floyd and doesn't take it, but steps up into the pocket and buys time for Gates to get open for another 1st down. This is also the only pure pass route run by any of the RBs this possession, with Mathews running a go.
"11" personnel. Royal runs an end-around for a negligible gain, saved only by a mean stiff-arm. This play is another call back to Whisenhunt's time in Pittsburgh, particularly his penchant for calling trick plays.
"21" personnel. Counter run to the right with Chad Rinehart pulling, and Mathews follows McClain into the hole. Another solid run to the right.
"11" personnel. Rivers has to sneak a short throw into Floyd on a dig, but this was because Seattle's defense does a nice job in coverage. We see a concept deployed for the 2nd time (the Cross + Dig + Cross). Earlier it was done with 2 TEs and a WR, this time with 2 WRs and a TE.
"22" personnel (2 RB, 2 TE, 1 WR). Fluker does a nice job burying his man in the pile and gives Mathews the room to go over the top for the 1st down. I would have liked this even better had Mathews gone over the top with both hands covering the ball. Hey, at least he got up after the play. If you noticed, McCoy pulled him immediately after this play.
"11" personnel. This play was the best timing Rivers had on the short throws, hitting WR Keenan Allen on a dig for a 4 yard gain.
"11" personnel. Rivers gets greedy on this play, trying to hit Floyd on an out-and-up for a TD. His discomfort is also evident when you notice he misses the quick toss to Gates, who sat down in a zone hole and would have been near a 1st down.
"11" personnel. In this case, Rivers doesn't take the Dig to Floyd, who has a chance for a 1st down with some YAC. Rivers scrambles instead, coming up just short of a 1st down, and forcing a short FG attempt.
By the way, this play is a clear sign that McCoy does what all smart coaches do, and that's steal from the best. This is the play Peyton Manning goes to when he needs a 1st down. It comes from the Manning-Tom Moore playbook in Indianapolis, and Manning brought it to Denver (and McCoy) last year. Variations of this play went for an Eric Decker TD against the Chargers in Denver last year, and also went for a Dallas Clark TD against the Chargers in the 2008 AFC Divisional Playoff Game in Indianapolis.
Here's my takeaways from the opening drive.
- Rivers clearly needs more work on the timing for quick routes.
- McCoy and Whisenhunt are going to use lots of Digs as blitz-beaters.
- Whisenhunt still likes to call trick plays.
- D.J. Fluker may not be great against the pass, but the coaches love running behind him.
- Mathews looks better with blitz pickup.
- The "Cross + Dig + Cross" concept already looks like a staple for this offense.
