So as you can see TT was very active in Free Agency when he first got here and as the team he wanted took shape he was less and less active. I think lists like this are fun to look at it. TT obviously hit gold with Woodson and Pickett. Got a solid player in Peprah and good play out of Green when we won the superbowl. Kuhn is a hard-working grinder who is a great addition to our team. The rest of the players are players that never really panned out though. Ted seems to hit more gold in the draft than in Free Agency and I am not sure why that is. Maybe his coaches have a greater opportunity at molding a better player and better personality if they get them right out of college then if they have already been in the league for a year or more? I am not sure but I do know TT drafts very well and will get more solid players on average than almost any other team.
