Let's look at this systematically.
Per PFR, here are the total team targets since 2012, when Wilson took over at QB:
- 2012: 402 (405 pass attempts)
- 2013: 410 (420 PA)
- 2014: 432 (454 PA)
- 2015: 472 (489 PA)
- 2016: 548 (567 PA)
- 2017: 526 (555 PA)
I am focused on targets rather than pass attempts, because Wilson is typically among the league leaders in throwaways. I'm not aware of any source that explains the difference between team passing attempts and team targets in detail anywhere accessible, but I assume the difference is due to throwaways and spikes. PFF does, but for whatever reason their data is typically inconsistent with PFR, nfl.com, etc., so I prefer to stick with PFR.
I know Carroll wants to pass less and run more, if possible, and they showed that in the draft, drafting RB Penny and run blocking TE Dissly among their first 3 picks in this year's draft. But the defense will probably be worse this season and offset that desire. So I will assume those factors wash out and result in the same 555 pass attempts as last season. I will reduce that by 20 to 535 team targets to account for throwaways and spikes.
Here are the TE targets since 2012:
- 2012: 87 = 21.6% of total targets - Zach Miller was lead TE
- 2013: 88 = 21.5% of total targets - Miller was lead TE
- 2014: 84 = 19.4% of total targets - Willson was lead TE
- 2015: 127 = 26.9% of total targets - Graham was lead TE
- 2016: 123 = 22.4% of total targets - Graham was lead TE
- 2017: 133 = 25.3% of total targets - Graham was lead TE
Graham and Willson combined for 118 of those 133 targets last season and both are gone. The Seahawks added veteran Ed Dickson and 4th round pick Dissly. They also seem to expect Vannett to take a step forward and significantly increase his involvement in the passing game in his third season. Altogether, I think it is appropriate to project this group for 110 targets, which is 20.6% of the targets. Per the data above, that would be the second lowest percentage for TEs in Wilson's career.
Here are the RB targets since 2012:
- 2012: 76 = 18.9% of total targets - Lynch was lead RB
- 2013: 67 = 16.3% of total targets - Lynch was lead RB
- 2014: 74 = 17.1% of total targets - Lynch was lead RB
- 2015: 80 = 16.9% of total targets - Jackson was lead RB
- 2016: 98 = 17.9% of total targets - Michael (!) was lead RB
- 2017: 104 = 19.8% of total targets - McKissic was lead RB
I expect Carson, Penny, Prosise, and McKissic to make the final roster. McKissic was very good in the passing game last season, and Prosise has been good in the limited games in which he has been healthy. Penny is expected to be good in the passing game. Altogether, I think it is appropriate to project this group for 100 targets, which is 18.7% of the targets. This fits reasonably well with the trend shown by the data above (i.e., increasing percentage to RBs over past couple of seasons with notably higher pass attempts).
I have 325 targets left for the WRs. Assuming Marshall does not make the final roster and assuming no major injuries to these players, I could see those breaking down like this:
- Baldwin: 125
- Lockett: 90
- Brown: 45
- Darboh: 35
- Others: 30
This would blow away Lockett's career high of 71 targets, but it probably does not make him particularly valuable for fantasy purposes. Using his career average catch percentage, ypr, and TD percentage, that would project him to 59/785/4 receiving. It seems reasonable the he could improve that TD number, maybe to 6 TDs.
But one thing about Lockett in his career to date is that he has been a boom/bust kind of player, which makes sense given he has operated largely in a deep threat role. He has 4+ receptions in 18 of 49 career games. That scales to just under 6 times every 16 games. In his other 31 career games, he has 54/685/2 receiving... that is 4.3 ppg in PPR. So it has historically been difficult to trust him enough to start him in fantasy, other than in return yardage leagues or really deep lineup leagues.
To more directly answer
@FreeBaGeL, I think most of the targets vacated by Graham stay with the TEs and most of the targets vacated by Richardson are spread among the top 4 WRs, Baldwin, Lockett, Brown, and Darboh. I see Lockett with +19 targets, which is +27% over last season, his previous career high.
Seattle is my second favorite team, and I like Lockett a lot as a NFL player and would love to be wrong about his fantasy potential. I just don't see the optimism for fantasy that many of you see.
