Risk/Reward is to go pro.
1. He is already in his 4th year so the pros will already have enough tape on him so another year of college has limited upside re: draft level. Sorry, he isn't going to win the Heisman and he isn't going to be a 1st round pick.
2. The risk of injury, and he saw what injury cost Morrison, offsets what marginal one year difference he makes versus salary level in the pros as well as getting to his 2nd contract which is where the real money is.
3. Assuming he isn't a 1st round pick, the last pick in each round slotted annual pay is as follows: 2nd: $1.8, 3rd: $1.5, 4th: $1.2. Since Love, a Heisman candidate, is reported to earn about $1.5M in NIL, Price is unlikely to get close to that and the difference to last pick in the 4th round money is therefore minimal.
All in all, I bet he goes because his upside is getting to the pros sooner versus staying in college.
