Mailbag Part I: Is GM Ryan Grigson on a short leash?

Here's Part I of the Colts Mailbag. Part II will run Saturday afternoon.

Wells: Why would GM Ryan Grigson be on a short leash? All he has done is win since the first day he arrived in Indy three years ago. Three straight 11-win seasons, three straight playoff appearances and back-to-back AFC South titles. That doesn't sound like a general manager who needs to be on a short leash. Has Grigson missed on some of his offseason moves? No question. The release of safety LaRon Landry this week and failed trade of running back Trent Richardson prove that. But no general manager bats 100 percent with his moves. A move that doesn't get talked about much is how Grigson was able to land Vontae Davis, who has become one of the premier cornerbacks in the league. Grigson's job status is safe. Wells: You never know what can happen, but I'm willing to say you probably have a better chance of winning the lottery than the Colts bringing Richardson back next season. The Colts gave Richardson countless opportunities to prove himself and he continued to let them down -- from lack of production, lack of accountability and not maintaining his weight. The door isn't closed on Richardson, but it's getting very close to being slammed on him. Wells: Not in the first round. The Colts need to add some depth at that position, and they might do it during free agency. They have too many other areas they need to address to take a receiver in the first round. I can see them selecting a receiver in the later rounds. Wells: I'd say at this point, the Colts are more likely to go with a veteran/young player. That veteran should be Mike Adams. They don't necessarily have to draft a player to start with a veteran. The Colts can sign or trade for a young player at that position. Wells: The Colts, and just about every other NFL team, would love to land Ndamukong Suh and Adrian Peterson. They're two of the best players at their position in the league. I'm with others in saying the Colts should go after Suh. Suh has had issues in the past, but at least he makes an impact on the game. It's well documented that the Colts have had players who've had character issues. Not all of those players helped them win games the same way Suh would. As far as Peterson goes, ESPN.com Vikings reporter Ben Goessling wrote Thursday that Minnesota would welcome him back to the team. Wells: I don't know who the Colts will draft, trade or sign in free agency at running back because it's way too early to tell right now. As far as players who were on the roster last season, I expect Vick Ballard, Daniel Herron and Zurlon Tipton to be at training camp. I expect Tipton, who ended last season as the backup running back, to end up back on the practice squad. Don't rule out Ahmad Bradshaw, either. His biggest issue is his health. He has to work his way back from a broken fibula.
