According to NBC Sports Bay Area's Monte Poole, House is only receiving a non-guaranteed training camp contract, which allows the Warriors enough flexibility to still potentially re-sign Patrick McCaw.
House appeared in 23 games for the Phoenix Suns this past season, averaging 6.6 points and 3.3 rebounds. He scored a season-high 22 points in Phoenix's 117-100 loss to the Warriors on April 8.
House's arrival continues a relatively understated, drama-free summer for Golden State. After winning a second straight NBA title, the team didn't need to make wholesale changes.
DeMarcus Cousins is the Warriors' biggest offseason addition, and it's unclear what he'll be able to contribute. He's coming off a major Achilles injury that will almost certainly keep him out for the first few months of the regular season.
House spent part of the 2017-18 campaign in the NBA G League. The 25-year-old averaged 17.9 points while shooting 38.6 percent from beyond the arc.
Managing the workload of Klay Thompson will be one of Steve Kerr's many tasks as he approaches his fifth year as Warriors head coach. Golden State selected Jacob Evans with the 28th overall pick in the 2018 NBA draft, and having another 2-guard in House will provide Kerr with further cover when he wants to rest the four-time All-Star.
