Every team has its drafts busts and booms as well as the same with Free Agents. There are advantages and disadvantages to both.
TT is confident in his (and staffs) ability to scout college talent, maybe at times a bit too confident? I think most of us are in agreement that he doesn't dabble in FA enough, especially this year with some major holes not being addressed (ILB/TE). I get his sense of pride in the draft and develop philosophy, but I think its time he loosens the bank roll up each year and puts a few more proven vets on the field, not only for their skills and experience but for their veteran leadership. Said this many times, but I wonder where our defense would be today if Charles Woodson was still on it.
The Packers had a major hole at safety in 2012 and 2013. The hole was not addressed. The Packers had a major hole at ILB in 2014 and again in 2015 and it was not addressed. The Packers had a hole at TE in 2015 and it was not addressed.
The Packers had a hole at OLB opposite of Clay between 2009-2013 (yes, even in the Super Bowl run it was manned by scrubs like Zombo & Walden) and it did not get properly addressed (the Nick Perry selection failed to fix the problem) until 2014, when TT signed his first prominent veteran free agent in 8 years Julius Peppers.
When Carolina lost a good pass rushing DE to IR (designated to return) in Charles Johnson earlier this year, they traded for Jared Allen. With a number of young CBs to break in on their roster (just like GB), the Panthers signed Peanut Tillman last offseason for insurance. Neither of these moves were flashy, risky, or expensive.
Many Packer fans scoffed at NE when they went "all in" by signing high priced Free Agents Browner & Revis last year, saying they'd never stay long and would stunt the development of younger players (the mantra in Green Bay). Well, Revis and Browner are indeed gone (after helping NE win another Super Bowl) and poor NE, that franchise has been decimated right? It must have been decimated, because not only did NE go out and sign even more veteran free agents this offseason but Belichek has traded for 3 players from other teams since the start of this season.
At some point, one would think that even the most diehard loyalists would acknowledge the hole in TT's game - his (reluctance? inability?) to acquire veteran players to plug holes in the Packers' roster.
