Well, yeah, there's a big drop off from picking #1 overall to #15. To be honest, usually there are 5-8 game changing players in a given draft. Picking them is loaded with peril. Remember Bledsoe vs Mirer? Players like Tua, Fields, Lance, Wilson, Lawrence are still finding their way. Getting Mac amidst all the different possible outcomes is not bad, IMO.
I'm no where as negative as you are on Mac. He hasn't been his sharpest in the last two games, even he says so. Hitting the wall is a real thing for a rookie. Yet I feel he is good at reading defenses and is good moving in and around the pocket. He's never going to be an elite runner or gunner. The comps we had coming out of college were Chad Pennington, Derek Carr, etc. He's on track to be that level player with IMO a chance of being better than that. It's too early to call.
There really are much more QB-needy teams than us right now, so moving away from Mac would take a ton of resources, and would be really out of character for the kind of team building this staff usually does.
I get it, the idea is to get a MVP candidate level starting QB, but if it were easy there'd be 32 guys competing for MVP rather than just one or two.
Really what we need to do is what we're doing, keep improving the team year by year and put Mac into the best position we can for him to "take the leap" next season or the one after that. We are really in no position to get another QB with high potential via draft or FA any time soon, the cost is simply too much. We're in a much better position if we keep coaching Mac up, help him continue to get stronger both mentally and physically, and keep building the team's overall talent level.
Then in year 4 of Mac's career, unless the growth curve really kicks in, we're in a big spot just like CLE with Mayfield. Do you sign him up long term? Who knows, the world will be a different place by then. Chances are BB will hang them up at some point along that curve. Time will tell.
