In my opinion, losing either Bully Ray or Devon would be a tremendous blow to the TNA roster. Both have respectively busted their asses to get over with audiences (and done so successfully!) and are now solid veteran performers 100% willing to commit to angles, lend name recognition to the company and put over rising talent whenever asked.
Were I to rank the importance between the two, clearly Bully Ray takes the advantage. Less than 18 months ago, the guy was a seasoned wrestler who was starting to show signs of displeasure with his status as a tag team specialist. He appeared stagnant and bored. Seemingly to appease him, TNA offered him a solo opportunity. It's been an incredible pleasure to watch what's happened since that time.
TNA not only allowed him to explore and develop a new character, he ran with the ball! Slowly the company built him into a marketable, totally credible and utterly believable World Heavyweight Championship contender. Despite originally being a skeptic, now I can buy Bully Ray going over Jeff Hardy, Mr. Anderson, James Storm, RVD or any of TNA's other top-tier talent. In fact, at this point, I could totally back a Bully Ray title run!!
For TNA to invest so tremendously in Bully's character, getting him over so believably with audiences, then let him go would be foolish and short-sighted. It would also be a shame for him -- because, even if he was signed to WWE (and he would be), he wouldn't get the kind of opportunities he's receiving in TNA.
Meanwhile, Devon's run as TNA TV champion shows the company has faith in his ability to work with and elevate younger talent. They support his marketability and capability to provide quality, TV-worthy matches. He's turned their secondary title -- little more than a comedy act when worn by Eric Young -- into a legit championship, with defenses week-in and week-out. While he's not moving in and out of the main event picture like Bully Ray is, it would take little effort to place Devon in those circles as well. TNA knows this as well.
That said, neither of these men is "expendable." Both are doing their jobs in TNA to the best of their abilities, and the results are obvious. While I enjoy Devon less than I do Bully Ray -- despite long believing (probably quite mistakenly!) that Devon was superior in the promo/interview department -- that bears little on the value each presents to the company.
It would be truly fool-hardy for TNA to invest such a tremendous amount into these men, then simply let them waltz out. I, for one, hope management does all it can to secure both for another year to 18 months. The possibilities of what both can accomplish in that time excites me.
And, without question, I believe completely each is well worth TNA's investment.
