The acquisition of Ted Ginn today means that it is very unlikely that the 49ers will use a first round pick on CJ Spiller or draft a WR in the first three rounds.
Spiller's supporters touted his ability to help in the return game and make the offense more dynamic as reasons to use a first round pick on the RB out of Clemson. Ginn covers the need for a return man and bringing him to the team will likely result in Niner fans seeing a lot more three receiver sets with Ginn, Morgan and Crabtree.
Frank Gore is still only 26 years old and is a back that needs a lot of carries to get him going. Spiller would only see very limited time on the field and the Niners would be better served using a first round pick on someone who can get on the field for more downs per game.
This does not mean that the 49ers won't draft a change of pace back. If they address their RT hole in the first they may look to Jahvid Best if he is available in the second or Dexter McCluster in another round.
For all those of us hoping for Jordan Shipley, this trade ends that speculation as well. In the first three rounds the Niners need to get a CB, a safety and an RT. They could also use a pass rusher at either an OLB spot or more likely a DE. If they draft a receiver it will be in a later round.
Overall, this is a good trade for the Niners. They give up very little to get a very good return man and a WR who could thrive when put in a position where he does not have to be the number one or number two option. It definitely changes the outlook for the upcoming draft.
