I think you hit on a very important part here. Fans (and I'm sure Gms) don't want to miss on the next Mahomes. And it will cause a team to over value someone if they think they may be that person.
There is a risk of someone else drafting Love but the question is, is Love a QB the franchise cannot live without? I don't know the answer to that question.
Mahomes is a big, confident quarterback who brings a variety of physical tools to the party, but he's developed some bad habits and doesn't have a very repeatable process as a passer. Mahomes' ability to improvise and extend plays can lead to big plays for his offense, but he will have to prove he can operate with better anticipation and be willing to take what the defense gives him in order to win from the pocket. Mahomes will be a work in progress, but he's a high ceiling, low floor prospect.
Who does this sound like
Didn't help the Redskins the year we got Luck, and it didn't help the Chargers the year we got Manning. Sure picking high means you have a higher chance of hitting a homerun, but the Jags and Browns prove that picking high isn't a sure bet no matter what..
