For one, not being under center limits your run options.
For two, you have to take your eyes off the defense for a second when you're recieving a shotgun snap, which doesn't seem like much but you can lose track of, or not see a blitzing player that shifts quickly pre snap.
Is that it won't be spent learning new mechanics with the fear that it will all break down under the heat of a real pass rush. Rosen has already mastered the mechanics of his position and so the focus will be solely on learning an NFL playbook and NFL defenses...and becoming bigger and stronger.
Just because he is the one prospect who will be ready to start from day one, doesn't make that the suggested strategy. Build a a successful team around Eli that can be passed down to Rosen in a year or two the same way the high-functioning Niners offense of the 80's was passed down from Montana to Young (and then to Garcia).
Whereas on the one hand it's good to know what one is about on O (run blocking style and why you use it)
it's also not good to get wed to much to any particular formation (11p shotgun)
So, if your facing a wide 9 pass rush (or whatever the fuck it's called) it may be good to be able to run quick hit runs and QB runs off center at times to force the DL and lbs to stay in closer. Just a made up example of why you never want to totally forget the 'old ways'.
I think Rosen could start week one. Darnold, Mayfield, and Allen really need to sit and learn behind a veteran.
I know everybody understands this, but rookies almost never come in and light things up. Marino did. Wilson did. Watson did for a short time this year. But if you look at Peyton Manning's rookie year, John Elway's rookie year, most of the great QBs who started as rookies, the first year you live with growing pains. Rosen may start Week 1 but then the fans have to lower their expectations. If you get a guy who plays like an elite QB in his rookie season, that's a bonus.

That's why you have guys like Davis Webb, who have a lot of raw talent, who are not ready for the NFL.
