The moves teams make before the draft can better define their needs during the draft. Once the draft is finished, we'll have a better idea which positions teams still might target by adding undrafted free agents.
I'll conclude with a look at positions where the Seahawks still need depth.
Signed players: 63
Unsigned restricted free agents: 1
Draft choices: 9
Signed player limit: 80
Note: Draft choices will not count against the 80-man roster limit until they sign, meaning Seattle could initially sign up to 16 undrafted free agents without exceeding the limit, assuming restricted free agent Chris Spencer signed. The Seahawks' roster count of 64 signed players and unsigned RFAs or franchise players ranks near the league average.
Positional thoughts: The secondary is where Seattle needs numbers most dramatically. The Seahawks are among four teams carrying fewer than nine defensive backs. Seattle has eight. This position was already an obvious need area, and it would remain so even if the Seahawks re-signed Lawyer Milloy, as expected. The lower overall numbers drive home the point.
Seattle has 10 offensive linemen after signing free agent Ben Hamilton from the Broncos. That number is on the low side relative to the league average (11.0). The Seahawks are among 10 NFL teams with fewer than 11 offensive linemen. It's obvious Seattle needs to draft a tackle at some point, and probably early enough to get a good one.
