Doesn't have to do with draft strategy.
Something has changed since the Cowher years.
In the early to late 90's this team would draft a player and let him cut his teeth on ST's for a year or 2. Then once they've done well in that arena, they were given playing opportunities. This was an outstanding philosophy to develop role players to support the stars.
Recently, there are no Orpheus Royes, Lee Flowers, Jerry Osalvskis, Myron Bell, Fred McAfees, Hines Ward. The only person I can think of from the Tomlin years that was groomed like this was Isaac Redman who played a large supporting role.
This goes back to my general mantra that this team cannot develop players, period. It's a major f***ing problem of why they can't get over the mediocre to pretty good hump.
