Christian Mahogany is one of the few bright spots for Boston College this season, and it's understandable when watching him play. While it's true he has some real weaknesses, he also has qualities that could entice teams looking to solidify the interior of their offensive line.

One important point to note right away is that Christian can play on both sides of the offensive line without a noticeable drop in performance. Whether as a left guard or right guard, Mahogany will hold his own.
Another strong point is that he plays low; while his relatively short stature certainly helps, he often manages to maintain his power angle, allowing him to often have good Leverage.

In addition to playing low, Christian is a powerful player, naturally heavy, and makes defenders feel it. On initial impact, he can create displacement on the LOS (Line of Scrimmage) and make his presence felt. In general, he is well capable of meeting the physical challenges of powerful players, but it remains to be seen if this will still be the case against the big guys in the NFL.

His hand placement is quite good, but he needs to be careful about how he engages in the block, often doing so with palms forward. This is a good way to avoid holdings, but the issue is that he often does it with fingers pointing upwards rather than the classic W shape (which refers to the way offensive and defensive linemen place their hands with the two thumbs touching to form a W with the thumbs and index fingers). Not using this form could easily lead to minor injuries and, more importantly, missed blocks if his hands slip on the defender's jersey. This is a point to watch and work on.

In terms of FootworkMahogany is decent but can still progress by working on his Footwork de Pass Pro , as we'll see shortly. Otherwise, he has active legs, which is good, but he still tends to narrow his base when driving.
Thanks to all these points, Mahogany seems to be a solid Run Blocker for any system. 

Now, let's talk about the points that lower Christian's stock. Like many prospects, before even discussing his play, the first thing that drops his value is his age. Christian is already 23 and will be turning 24 during his rookie season. This alone will close the door on a certain range of players.

We also need to talk about his Footwork on Pass Pro where Christian sometimes takes too small steps, putting him at a disadvantage against explosive and fast rushers. Also on his FootworkI've noticed several block attempts, particularly in Pass Pro where he stops his feet, putting him directly in trouble against players who continue their effort. This is a point seen much less in his run blocks.

While Mahogany is powerful, he lacks finesse in his game, is not the most technical OL in the class, and may struggle more against skilled DTs in the NFL.
He sometimes gets shocked by a powerful and explosive punch, which can directly handicap him when it happens, so there's work to be done on this point.

Finally, regarding athleticism, Christian is a rather heavy player and one I find relatively slow, which could complicate his use in systems like those of the Niners or Dolphins that rely on a lot of screen passes. Moreover, this lack of mobility, combined with his heavyweight nature, really doesn't help with agility, sometimes leading to general imbalance in his movements to the second level.
