49ers' 53-man roster projection includes Raheem Mostert despite trade demand

The San Francisco 49ers open training camp for the 2020 NFL season on Tuesday at the SAP Training Center in Santa Clara, California. The defending NFC champions finished last season 13-3 and in first place in the NFC West, earning the No. 1 seed in the NFC playoffs. The 49ers return 21 starters as well as head coach Kyle Shanahan and coordinators Mike McDaniel (run game), Mike LaFleur (pass game), Robert Saleh (defense) and Richard Hightower (special teams). Here's a 53-man roster projection:

QUARTERBACK (3): Jimmy Garoppolo, Nick Mullens, C.J. Beathard

Garoppolo is entrenched as the starter but is now the time when the Niners deal Mullens or Beathard? The Niners like both backups and with so much uncertainty created by the coronavirus pandemic, it might be more prudent to continue carrying three quarterbacks than it has been in past seasons.
