I seriously can't believe people on these boards have such ridiculously short memories. Last year, Tannehill was being talked about exactly the same way we're talking about Nassib in this thread and a few other threads. Yet, most people think the Dolphins made a good choice in Tannehill.
Guess what, I truly believe Nassib is going to be a better QB than Tannehill. Does that mean I believe he's the 8th best player in the draft? Absolutely not. But QBs rocket up and are overdrafted, and it's not always as much of a "reach" as scouts scream on draft day.
Most people aren't saying Tannehill was a reach. Ponder just "led" his team to the playoffs (I won't get into this argument about who really got the Vikings there, but apparently we just acknowledge that the QB gets credit since he is, afterall, the QB). Locker is probably the "reach," and he would have been the #1 draft pick likely if he came out the year before.
People on here are foolish. Nassib's weakness by the OP are true, but you can teach throwing the long ball with touch, you can't teach foot speed (though he actually scrambles well), and you can teach people not to force balls into tight coverage. What you can't teach are smarts and arm strength. He has those 2. I'd love it if we got him in the 2nd, but who knows what happens between now and the draft. I'd be fine drafting him in the first if it came down to it.
