We have debated this before (and will again) but yes Dak would start on other teams, not all of them and not as many as his fans would like to think.
The questions is not whether Dak is good enough to start (he is) or whether he is a decent QB (he is).. the question is whether he is worth becoming the HIGHEST PAID QB ever.. and that question is stupidly easy to answer for anyone with two brain cells.. not in a million years.
Dak on a rookie wage was exceptional value.. dak on an 'average' QB deal would be OK value.. Dak on premium dollars is a waste of money and will set us back years. The dude is flat out not worth top dollar. There is no argument that a sane person can make that makes him worth top dollar. We have seen that without elite talent EVERYWHERE around him.. he sucked. He has a high completion rate because we had safe schemes and a lot of easy throws but his accuracy is actually poor with most analysts easily demonstrating that he rarely hits a receiver 'in stride' but rather behind and low. He is not a natural pocket passer and we know that 'mobile' QB's do not last as long in this league (his rushing yards have declined every year and will continue to do so. He takes more 'avoidable' sacks than any of the other top 10 QBs in the league.
So it is not just a question of skill (he does have some) but of value. Right now Dalton will easily give you the same output as Dak and at a fraction of the cost. Dak either needs to revise his demands or learn the hard way that this league is harsh when you are not lining up behind an all-pro OLine, with ProBowl WRs and a HOF HB beside you.
