Sure, we made a great pick 20 years ago. One approach is to believe that Belichick did it again with Stidham, and ignore the QB position. Several posters have embraced this boom or bust approach, even hoping for failure and low draft pick next year.
Matt Cassel netted a pretty good return for a 7th rounder as well.
Most late round picks don't make it, regardless of position. I'm fine going QB, because its the one position that truly could pay huge dividends. Maybe its the next Brady, that becomes a star late. Even if its the next Cassel, it got a year of success then flipped for a higher draft pick. If he flops, its like 80% of the other late picks.
Not a 6th or 7th rounder, but the Skins took Cousins in the 4th round of the same draft they took RGIII. Look how that played out. I only mention that in response to saying we already have Stidham.
If a guy has talent, he has talent. QBs slip through the cracks all the time. I see no problem drafting one late and seeing what happens.
