usually well managed doesn't have everyone to consider that it s reasonable to consider him to be a top 10 quarterback. And medical cannabis is still illegal in the NFL.Epilepsy is usually well-managed medically, these days, other than severe cases.
Some people swear by cannibis therapy, though....
To put another way, for many he was basically a $20M a year player next year, a starting QB, with th possibility of him being worth more or less. Now, would the same GM's consider that there has been ZERO loss in value? Of course not. There is a medical condition to be managed that COULD get worse or have unknown consequences in the future. This information cannot have no affect on his value.
The same folks may be willing to draft him at the same place, but be willing to pay less to move up.
