I've just watch Wentz's highlights from the past two games and is really good. I have a few thougths, tough.
1. This has no bearing on their performance but Dak is much smoother in his actions. Wentz reminds me a bit of a gangly teenager who's limbs grew faster than his sense of balance. He has a bit of a hitch when the runs and throws. Again, no bearing on their performance but it is a difference.
2. Wentz has a nice touch on his deep throw ... sometimes. I've heard some say Wentz is better throwing deep but I've seen him miss a few and we've yet to see Dak really let it go. He may be better but we need more evidence.
3. Wentz will throw into coverage and take more chances than what we've seen of Dak. He's more of a gunslinger trusting his arm strength to fire it in there. He hasn't been picked off yet but he's not a selective as we've seen Dak so far.
That's about it for my 15 minutes of scouting. I would be very excited to have either of these quarterbacks.
