The 63rd pick is in and SB Nation's Colts community, Stampede Blue, has selected...
Syracuse DT Arthur Jones
Jones' strengths are his burst off the line and his quickness. He doesn't have a solid set of pass rushing moves, but that is where defensive line coach John Teerlinck comes in. If anyone can develop Jones as an interior rusher, it's him. Jones is also a very good and violent tackler. He sheds blockers well, and his competitiveness really sets him apart from other players. He can also play "anchor" tackle, utilizing his size and strength. The only red flag with Jones is a history of injury, but one thing I liked reading in his scouting report was he played through injuries at Syracuse and still produced. He's a tough guy. One needs that to win in the trenches in this league.
This early for a defensive tackle is a potential risk. You'd basically be giving up on Moala after a season, even though he might fit best as a 3-4 end. I also really like the potential of Muir, even though he wasn't given a longer-term contract. But BBS is right in that Jones would fit the scheme pretty well and has some versatility.
Haven't the Colts been searching for a defensive tackle for a long time? Maybe a bit early, as MTD suggests, but I like the idea of adding talent to the defensive line.
