I never liked Jared Goff....I'll put that out there before I continue.
1st, he's lanky. He needs to put on some strength in order to play against the Ravens, Steelers, and Bengals defense on a weekly basis with no running game to speak of.
2nd, he plays in the Air Raid offense (which is the WORST version of the spread offense I would want my future QB running, because any average QB can put up numbers in that offense. Notable Browns QBs Tim Couch & Johnny Manziel both ran this offense in college to tons of pretty stats as well).....in the Pac 12 at that, a conference known for being the 2nd weakest conference when it comes to defense.
3rd, and instead of explaining it myself, I'll let the article that was posted above speak for me:
So he was known for pressing and trying to do too much, because he didn't have a ton of help around him at Cal.....and then putting him on the Browns in the NFL is a concern for me
Now, I DO agree that the Browns should take the chance on Goff, being that they have no future QB on the team (Money Manziel is gone, we all know that

), but Im not sold on him at all as being a franchise QB right now, and the Browns have no choice but to pick him imo.
