The top gainers in yards/game from 2004 to 2005 (among WRs with over 50 targets in 2004) were Larry Fitzgerald, Joey Galloway, Anquan Boldin, and Santana Moss. These four really stood out from the crowd --
With such a small sample group, we should be careful drawing easy conclusions. Let's take a look at each situation.Fitzgerald - a 2nd year WR who had the traditional breakout.
Boldin - a 3rd year WR returning from injury.
Both played for the Cardinals so let's compare 2004 and 2005. In 04, the QB was Josh McCown. In 05 it was Kurt Warner (generally).
Attempts - 533 (04) and 670 (05)
Completions - 299 (04) and 419 (05)
Pass Yds - 2882 (04) and 4437 (05)
Pass TDs - 14 (04) and 21 (05)
Arizona moved from one of the worst passing offenses to the best in one year. Certainly you could attribute some of this to Fitzgerald and Boldin. But you could also say a better QB who fit the system and a 2nd year in Green's system was the driving force. Finally, in looking for guys that will do this, we can't ignore the youth factor of Boldin and Fitzgerald. Should we only be looking for 2nd and 3rd year WRs with lots of targets? Which brings us to....
Joey Galloway - TB WR in his 11th season. Had not had a 1000 yard season since 1998. 2004 was his first year with the Bucs and he was hurt about half the season. Brian Griese was the QB for most of 04. Chris Simms was the QB for most of 05. But Galloway started putting up great stats with Griese at the helm. In fact, it's really hard to see where he had any dropoff or gain with the QB change (though I don't have game targets to look at). Bucs passing offense was actually worse than in 2004. Only situational factor you could attribute to Galloway was his 2nd year in Gruden's system.
Santana Moss - Was WR in his 5th season, first with the Skins. I'm not sure this can even be used with the premise because he switched teams, QBs, offensive schemes, etc. Nothing about Moss stayed steady.
I'd just be careful drawing neat conclusions here on these four players. Yes, the conclusion seems logical. Yes, it may even be likely. But I wouldn't jump all over Burress, Randy, Muhammed, Chambers, and Horn because of it. I'd say Galloway is the prime example in the above group. And so
maybe being comfortable with your QBs and your routes (system) in your second year makes a big difference (which also holds with Boldin and Fitzgerald).
If this is the case, only Muhammed and Burress really fit that mold.
