The San Francisco 49ers made it a point to improve the wide receiver position this offseason. But it’ll all be for naught if Brock Purdy doesn’t continue to play well and improve areas of his game. Offensive coordinator Klay Kubiak shared on Friday where the 49ers want Purdy to be better in 2026.  That area is his movement in the pocket. It’s a spot-on assessment. There were countless moments last season where Purdy would bail out of pockets too early. Rather than operate within the pocket to allow the play to unfold, he gets impatient, looking for the big play, and leaves. Sometimes it’s necessary for him to do that. But more often than not, it leads to him pressing. That’s part of why he holds onto the football for too long, which spikes the pressure rate he receives.  Kubiak sounds off on Purdy Jan 17, 2026; Seattle, WA, USA; San Francisco 49ers quarterback Brock Purdy (13) leaves the field following an NFC Divisional Round game against the Seattle Seahawks at Lumen Field.…
