Just like Abyz said, Tanny is not evaluating talent. He has his cs and scout team advising him. He does the leg work in contracts, trades and salary cap. I'll give you one example to prove u wrong...Curtis Martin. Oh yeah, where the eff did that "every FA acquisition he's ever made has been a bust, and the majority of his picks have been a bust". Revis, Harris, Mo, Cro, Keller, Mangold, Dbrick, Sanchez (playoff qb), Greene (great later in the seasons and playoffs), Braylon, Santonio (5th rounder that won us about 4-5 games in 2010 - I'd do it again), Woody, Faneca, Pace, Scott, LT, Rex...the list goes on and on.
Thank you for doing this so I don't have to go through it. Also to add on, LT, Cotch, Woody, Mason, Bray, all known players sent packing whether they were correct decision or not is another argument
The even bigger question is, given his injury history, why did he even chose to play football with lesser contact options available?
