Watson isn't good enough to be a "savior" of the offense (whatever that even means), but he's plenty good enough to *improve* the offense.
Last 2 seasons:
96 rec, 922 yds, 9.6 ypc, 76.8% catch rate
For comparison's sake...from 2017-2019, here are stats for a few other tight ends:
Watson: 96 rec, 922 yds, 9.6 ypc, 76.8% catch rate
Rudolph: 126 rec, 1198 yds, 9.5 ypc, 74.1% catch rate
Olsen: 62 rec, 708 yds, 11.8 ypc, 59.0% catch rate
Ertz: 214 rec, 2242 yds, 10.5 ypc, 70.4% catch rate
Howard: 70 rec, 1128 yds, 16.1 ypc, 70.7% catch rate
Cook: 130 rec, 1674 yds, 12.9 ypc, 63.4% catch rate
McDonald: 74 rec, 886 yds, 12.0 ypc, 67.9% catch rate
So I think what we'll see is Watson handling a lot of short-intermediate passes. He won't stretch defenses like Gronk could. But he's super reliable - 76.8% catch rate is fantastic (I think Kelce may be the only regular TE that has a better catch rate).
So far, in four games, the Pats have thrown 5 times to their tight ends. Granted, in very limited sampling, the results have been fantastic.
Izzo + LaCosse: 5 targets, 4 rec (80%), 77 yds, 19.3 ypc
They'll throw much more to Watson, I'm sure. Just opens up everything else a little more.
