The only stud you need is a franchise QB, not those at a skill position.
I'll give you a very relevent, yet painful, perfect example of this of two teams roads to SBs which follow identical tracks.
Two teams get fleeced in trades for great running backs....Buffalo and St Louis...for Marshawn Lynch and Jerome Bettis, respectively. Both will likely be HoFers, both improved the teams they went to greatly. Neither was the key for winning a SB. Lynch and Bettis were both on good teams with good defenses and no franchise QB.
Then two young guys show up and win early in their career: Wilson and Big Ben. And it wasnt until they got a QB that either one of those teams got over the hump.
I think Gurley is a great player, just not for a 1st. Fleece some other team like the above teams did to acquire one. Fisher has still never proven his method of building a team can win a SB and the guy has been around forever.
