This year, I concentrated mostly on QBs and WRs.
I study their system.
I review each of the pass pattern on each pass attempt to see how many are dump-offs, how many are short routes, how many intermediates, how many are medium deeps, and how many are deep routes.
I look at the pressure they faced (Big 12 and Pac 12 were lacking as compared with the SEC and Big 10).
I pay close attention to the pass attempts they are likely to make at the next level: From tight space where they don't have much room to step up the pocket, from having to slide or move to avoid pressure, and on the roll-out by design... to passes they have to make across their bodies, or into tight window (do they force it, or do they make the throw before the window tighten)...
The guys who impressed me were Wilson, Keenum, and Cousins.
RG III is next (but he didn't face as much pressure as the other 3).
Luck faced very little pressure when compared with those guys.
And like I said in one of the threads, there was one game in which the commentators noted that "Weeden's jersey wasn't even wrinkled, let alone having a grass stain".
I don't think Weeden is going to make it as a starter in the NFL.
Tannehill is a project. He's not accurate even when he wasn't pressured and the receiver was wide open.
He has a gunslinger mentality, throwing into tight window even when he didn't have to (ie. there was open receiver within the line of sight - within the pass pattern).
He knows very little about the defenses that he faced. His pre-snap and post-snap reads were poor.
Right now, he's not even a good thrower.
I remember Gruden once said "he has all the tools, but no tool box".
That was what I saw in Gabbert his last year at Mizzou.
Tannehill has a lot to learn, but he does have a lot of tools.
Can he put it all together or not is the million-dollar question.
