The difference is R1 and R2 QB’s that end up as career backups are QB’s that were drafted as starters and failed, sliding into the backup role. If Miami traded a second rounder for Rosen under the impression he would likely become a backup, they overspent. If they traded for him to be a starter and he becomes a franchise player, that would be a steal.
I almost agree. Let me tweak that.
"If they traded for him to be a starter" thinking he COULD "become a franchise player, that would be" justifiable. If he becomes a franchise player, that would be a steal." "If Miami traded a second rounder for Rosen under the impression he would likely become a backup, they overspent. "
I doubt any team drafts a R1/R2 QB with the idea of them becoming a backup. I doubt Miami did. But a backup at $2mm/yr isn't a bad deal.
