I agree with Jack.
Many of the people who dive "the Mac" frequently do penetration as there is much more to see on the inside than on the outside of it.
The Tacoma is a nice small wreck that one should take their time on. Overall it is in decent condition.
In the same general area as the Tacoma and the Material Service Barge (MSB) is the car ferry #2. This was a rail car barge that flipped over near the docks spilling the locomotives (they were recovered) then was towed out a bit when they weren't able to upright it and sank. It's in ~50', IIRC. Later The Army Corps of Engineers dynamited it to prevent from being a navigation hazard so it's mostly flat now and covers ~300' in area.
The Wings of the Wind is a nice wreck in the 45' range. Just the front portion remains with the windlass and bowsprit intact as salvage efforts after the sinking tore the back portions away. The rudder is still in place sticking out of the bottom if you swim back a little.
The Wells Burt is in good condition for it's age and how shallow it is. There is cables and rigging off to the side to see. It sank into the bottom a bit and is listing at about 30*s, the interior is mostly filled with mud but if you are comfortable in tight places you can swim under the decking in many spots. The Windlass and a few deadeyes are still there to see.
The Rotarian is in ~80' water and is pretty flat except for the centerboard.
The Buccaneer was intentially sank a few years back for divers. It's lies about 7 miles due East of Navy Pier at a depth of ~70' with the deck being `50'. Penetration is available for those trained.
Also near Navy Pier is the Flora Hill. She sank in 25' water and was also later dynamited by the Army Corps of Engineers as a navigation hazard. The boiler is still standing and there is a lot to see amid the wreckage.
