No QB is worth a 13th pick other than Mendoza in this year's draft. Just no.
Maybe in the second round but even then I have high doubts that any QB after Mendoza will be a decent QB.
Backups - yes but I would not take a backup QB until the 5th round at the earliest.
Unless Mendoza falls to #13, the Rams don't need a QB if the goal is to win SB 61. You get a shut down corner or trade a pick for 1. Then you use the other #1 to fill the next biggest need. Stafford is returning so let's go hoist that trophy in SoFi next season.
This team has a lot of talent so this is the year for McSnead to go all in and win it again. If we address corner, I'm good with drafting a blazing fast WR with good hands. (Like the 99 Rams took Torry Holt at #6).
I'm good with the Rams taking a QB with potential in the later rounds. We know that gems can be found there (i.e. Kurt Warner, although Warner wasn't even drafted)
