Steve Young and Alex Smith enthusiastically endorsed Thursday’s news that Jimmy Garoppolo will get paid more than anyone ever to work their old job as 49ers quarterback.

“Tremendously good news, and if I had $136 million, I would have given it to him,” Young said as he and Smith golfed together at the AT&T Pebble Beach Pro-Am.

A text alert on Young’s phone informed the former Niners on the front nine at Spyglass Hill Golf Course, and neither had sticker shock at the figures: $137.5 million over five years, with $90 million guaranteed in the first three seasons, per ESPN.

“At this point, with guys you think can go win championships, you’ve got to get them locked up and pay the market (rate), that’s how it works,” Young said.

Smith helped set that market rate last week when the Kansas City Chiefs agreed in principle to trade him to Washington, which promptly gave Smith a contract extension (four years, $94 million; $71 million guaranteed) once the trade can become official March 14.

“Good for him, good for him,” Smith said of Garoppolo.

Smith refrained from discussing his Washington deal in fear of ticking off the NFL before the trade is official, but he did offer context on the league’s ever-friendly market rate for quarterbacks.
