He's been talking up Daniels for a long time now. With genuine excitement in his voice. I think the reason we haven't seen him is because Pete wants Daniels to get some game experience in the return game before trusting him completely, and the safest way to do that is to wait for the preseason.
Doesn't mean the job is his, just means he is in the mix. The draft could factor in this, as there are some Seahawky WRs that double as dangerous returners.
I think Pete basically views Daniels as another Golden Tate, best case scenario. An agile and somewhat tanky WR who can make guys miss. Golden even threw a TD pass, and there might be some of those Randel-El type plays drawn up for Daniels, who will still be in the mix at QB. Given Bevell's proclivity for cute plays, I would be surprised at all if Daniels made the 53 next year.
