Boy, 10 years is a long time, a pretty big risk for any club. Not too many are going to take that risk. Albert is the best hitter in baseball for sure but will he be a 30 million dollar man in 2021? I'm not even sure he will be able to effectively play 1st base at 41 although it isn't beyond the realm of possiblity.
Look at Manny and his dropoff over just a couple of years. He is just 38 and his last two years have been ok at best. I just am not sure that King Albert can keep up that pace for that long.
I can't see St. Louis offering longer than an 8 year contract. This isn't a big market organization and they never got where they were by spending money on deals like this.
