He's got comparable stuff to Gausman who was drafted no.3 (or 4?) overall
Um, no he doesn't. Gausman consistenly threw his fastball 94-96 mph, and will occasionally run it up there at about 98 mph. Aaron Nola last weekend consistently threw his fastball 88-90 mph according to the radar on the tv. Nola is probably more of a low 90s pitcher, with great control. Gausman could just overpower hitters with his fastball, but what made him a top 4 pick last year was that he developed a great change-up to supplement his fastball.
As stated earlier, you really can't tell how a kid will pan out in pro ball. Those guys in pro baseball are amazing at their ability to turn a single mistake by a pitcher into a 2 run double. The biggest plus for Aaron Nola is that he won't have to take a few years to learn how to pitch at the pro level. He's already got the right mental makeup to be successful. Time will tell if he has good enough "stuff" to make it into MLB.
To be honest, had Aaron not grown up 10 minutes from Alex Box Stadium, and had he not had a brother already at LSU, he would have never stepped foot on a college campus. He would have been a top 10 round draft pick out of high school and would have received a large signing bonus to start his pro career. We, as LSU fans, were very lucky to get Nola to LSU for 3 years.
