The way I'm thinking about it (today) is that there is no other WR prospect even remotely in the same universe as Calvin Johnson, but there are several QB prospects that aren't that far off from either Russell or Quinn. Stanton, Kolb, Beck, etc.. they're really all pretty solid.
So, I guess you can count me in on the Calvin bandwagon at #1 overall. However, I'd very much prefer we trade down to #3 and pickup whoever is left. If that's CJ, great. If it's BQ, alright. If it's JR, fantastic.
