You can find those positions on the street. The importance of QB makes it different IMO. Throw numbers at the position and you'll probably find a diamond sooner than if you keep following the current strategy.
Adding competition for Manuel is not a bad move, especially for a late round pick. If he can't handle it, he's probably not the guy anyway.

We've spent the last 15 years trying to find guards, DBs, etc off the street and have yield awful results.
sure, DBs is a position you typically need to invest in and the Bills have done that. Do you think they need more DBs over a QB?
As for OL, my sense is there are a lot of starters at the position around the league that went undrafted. Or you can just pick up other team's scraps like the Bills did with Legursky, Urbik, Rinehart, etc. Wasn't the line pretty good under Gailey with mostly players that were undrafted by the Bills? I think a lot of it is coaching and scheme, as much as raw talent.
Undrafted Jason Peters also worked out a lot better than #4 overall pick Mike Williams.
so your position is you want to roll with Manuel, Thad, and Tuel and don't bring in any new competition no matter the cost? They spent late round picks on two safeties last year and a kicker. Why not take a lottery ticket QB at some point?
