IMO Lockett's usage will go up. It has already been announced he will start over Kearse.
Last season, the Seahawks had 234 passing attempts in the first 8 games and 255 in the last 8 games. It seems reasonable to project 500-520 passing attempts, with some potential for more. I'll assume 500 to be conservative.
Off the top of my head, I expect targets to break down something like this by position group:
- WR - 295
- TE - 125 (assuming Graham targets are lower in the first half of the season, keeping overall TE targets down)
- RB - 80
Further breaking down WR targets, assuming all of the named WRs stay healthy, I expect something like this:
- Baldwin - 100
- Lockett - 95
- Kearse - 65
- Richardson - 25
- Others - 10
Lockett had 69 targets last season, and Baldwin had 103. So I see Lockett getting a significant increase and Baldwin holding steady. But I think TD distribution will be distributed quite differently than last season. So I expect Baldwin will not offer good value at his ADP, and Lockett will.
Of course, Seattle could theoretically throw quite a bit more, and another 50 attempts would significantly boost the value for both of these guys.
