I play in some super flex leagues (I assume that's what we are discussing here w/ 2 QB) and I don't think the top 3 QBs would or should go with the first 3 picks.
A top WR like Watkins still has a ton of value and QB is really deep right now.
I'm just thinking about one of my super flex teams (as a real life example, 12 team PPR) that needs a QB and it comes down to:
Would I rather replace a Carson Palmer/Mike Glennon platoon at QB2 with a guy like Bortles or would I rather replace Brian Hartline/Emmanuel Sanders type guys as WR3/Flex options with Sammy Watkins?
Seems like a no brainer that Watkins makes more sense. And that is probably true for a majority of rosters, not just mine.
Is it guys that don't play in super flex leagues just assuming that any starting QB is mega-valuable or are guys that play in super-flex also feeling this way? Don't get me wrong, an elite QB is worth a ton. Arguably more than an elite WR. But elite WRs are worth way more than middle of the pack, non-elite QBs.
A few points where I would disagree:
1. I find it a bit unlikely that, barring a trade, the owners of a premium pick has a platoon of Palmer/Glennon as QB2. It happens for sure, but its rare. I think its more likely that they have Palmer as their #2, and Sanchez as his #3. Or even Palmer/Glennon as his entire QB stable. If they had three starting QBs, they can trade one of them rather easily to improve their roster -- and then they can take the more valueable player.
2. Watkins isn't a sure thing. And more importantly, his value takes a much bigger hit if he doesn't produce WR1 numbers in the first couple of years. Top 10 overall picked QBs have a much longer period where they are still considered valueable. If Bortles *merely* turns into another Bradford, that is still a very valuable piece to have a 25 year old starting QB.
