Watson only played 6 games in his rookie season before going on IR. He was 3-3 over those first 6 starts (interestingly...same as Luck). But if we are talking about playoffs...we can only look at their first two trips to compare (they were both in their age 23 and 24 seasons as well). And in that comparison...they were both 1-2...but Watson had better stats.
Watson did have Hopkins the past two years...but he only had a good defense in 2018 (last year's defense was awful...just look at what JB was able to do...or what happened in the Divisional game). The run game (led by Lamar Miller and Carlos Hyde the past two years) was solid because of Watson...who is a threat on the ground and chips in 400-500 yards and half dozen TDs on the ground each year.
But I was only using the Luck comparison as one data point...the list of good-great QBs who took a few seasons (or playoff trips) before winning big games in the playoffs...is long...like really long. The fact that Watson hasn't won any big games by age 24...is not unique to him. And I don't think it's a fair standard...because nearly all of these other QBs peaked in the age 27-32 range...and that is when they started winning big games (aside from the clear best two QBs in the NFL right now...Mahomes and Wilson).
Watson will only be 25...so I think it's far too early to judge him on his ability to win big games. His stats...both in the regular season and playoffs...show he's a top 10 QB. I would take him in a heartbeat if I could. My real fear is that BB somehow gets his hands on Watson.
It is sad...and not to sound too cynical...but that's where the money is...in treating the symptoms...not the cause. Healthy people typically don't have medical bills or have monthly prescription needs. But that is a whole other rabbit hole to go down.
