I'd probably take the green pill. Hockey IQ is a skill that isn't too reliant on physical attributes, and even with short stature the ability to read plays, get into the right position and make a good first pass would make Hartmann a very good defenseman. Just using the power play as an example, size isn't a deal-breaker when you can always make the right pass to the open man and set up players for wide-open tap-ins. On defense, having a great hockey IQ is critical for being able to get sticks in the lanes, avoid falling for the misdirections of opposing forwards, and other defensive tactics. While physical abilities are usually the first to go as a player ages, something that is made more significant by the lack of height, another upside of taking the green bill is that with a high hockey IQ, you'd be able to use your intelligence to make up for your lack of physical ability and prolong your career significantly.
