He probably wanted to remain on the west coast. HS, college, pro all on the coast. So, SF/LAR/LAC/Oak were on his list. SF/LAC run the same system.
I don't think SF is a Superbowl favorite this season. Could make the playoffs, but that is tough given how stacked the NFC South is, and GB has Rodgers. Dallas should rebound without all those distractions with Zeke. So, hard to see them getting a WC birth.
Think the 2019 season is a more realistic shot for them to make the playoffs.
The breakdown of the contract will be interesting. SF has a tonne of cap space so, likely will be front loaded contract. No way year 3 is guaranteed. Would like to see how much is guaranteed in year 2.
