Scouts/coaches take a look at how a QB plays relative to the level-of-talent surrounding him.
Thorson has played 3 seasons with NU's GOAT at RB and last year with the best receiver to have come thru Evanston in some time.
Yes, Thorson has better physical attributes than Trevor, but he's not where Siemian was in his last season w/ the 'Cats.
But that's not surprising as Thorson was pretty raw as a passing QB (like Kafka-level raw); QBs like Siemian and Bacher were more polished passers coming into the program.
Thorson still needs to work on keeping his mechanics more consistent and as I had stated before, needs to work on that next level of QB play, extending plays with his legs to set up the pass.
That's something Persa was great at and what Siemian did pretty well when McC finally let Trevor out of the pocket; have also had issues w/ how McC has handled Thorson in that regard.
Too often, McC has kept Thorson stationary in the pocket and not making use of his speed (for a QB).
Now, not necessarily asking for how Kafka was used earlier in his career, but what's the use of recruiting QBs with above avg. mobility if you're not going to use it (have used it more often the past few games)?
But when Thorson runs, he's still more of a tuck it and run QB than trying to extend the play and looking downfield for an open receiver.
Also, while he has more straight-line speed than Trevor, Clayton is more stiff has a runner (has less wiggle).
If Thorson gets a 2nd rnd grade, then he should leave; but don't think he'll get that unless he really pours it on these next 2 games and in the bowl game.
A 3rd rnd grade makes the decision a 50-50 proposition, maybe leaning more to coming back.
