QBs in general are really a crap shoot. Nobody really knows how good someone will be until the get in the NFL. The Bears could get a starting caliber QBs in the 2nd IF they do their job right. There have been a lot of late round QBs that turn out to be successful. I just hope the Bears keep taking chances until the get it right. They need to use their 2nd on the best prospect available and if they will this year do it again next year.
Ideally, you'd always want to just take the best football player available just to better ensure you're getting an impact player. With QB though, there's usually that position need that need be fulfilled right then and there.
QB seems like more of a crap shoot than it truly is. There's just not enough really good ones from year to year to fill the needs of all teams so you'll see interest sparked in this or that QB when teams run out of other options which happens fast.
You'll see a lot of what these QBs did in college when they get to the NFL. If they were mobile, they're not going to be less mobile in the NFL. If they're accurate, they're not suddenly going to become wildly inaccurate. If they could read D well, they'll keep doing that well. The problem is many are overhyped because there is that high demand for QBs and a very short supply of very good ones.
Seattle's GM was sold on Wilson long before that draft, even after taking a FA QB. Never wanted to show his hand to lift Wilson's stock but was 100% sold on him as was his HC. No crap shoot for him. He got what was expected and more.
Same with Baltimore and Jackson. Amazing athlete and nobody questioned that but they did question whether he could be a QB in the NFL and was open to being a receiver. Newsome never questioned. He liked what he saw and was 100% sold on him as a QB. Never interviewed him or so much as inquired about him before the draft in order to keep his draft stock as low as it was, then traded up for him when they thought they had pushed their luck too far during the draft. No crap shoot. Got exactly what was expected.
A guy like Rodgers lasts longer than expected so then comes a team smart enough to realize even though they weren't looking for QB in this draft, they couldn't possibly resist taking him. No crap shoot. Just fell into their lap.
Look at Trubisky's draft class and if you looked at the film of all 3 top QBs, don't see why so many put Trubisky ahead of the other 2. You'd first have to wonder why he couldn't beat out a bum for 2 years. And if you were to watch the Sun Bowl, a game Pace has pointed to that sold him on Trubisky, you'd see all of the bad you see now. Bad reads, inaccurate deep ball, apprehensive with certain plays etc. Of course the type car Trubisky drove also helped to win Pace over so not as if he was being especially thorough in his whole QB analysis.
Meanwhile, had you looked at Mahomes, you could only be impressed. But he was doing things QBs shouldn't be able to get away with so was said he needed some good coaching. Enter Andy Reid and the Chiefs 100% sold on Mahomes to the tune of trading up with a swapping of their 1st round pick coupled with a 3rd and a 1st round pick in the following year. And then it turns out Mahomes could still do those things, that QBs shouldn't be able to get away with, at the NFL level.
